GENERAL DESCRIPTION
The OP97 is a low power alternative to the industry-standard OP07 precision amplifier. The OP97 maintains the standards of performance set by the OP07 while utilizing only 600 A supply current, less than 1/6 that of an OP07. Offset voltage is an ultralow 25 V, and drift over temperature is below 0.6 V/C. External offset trimming is not required in the majority of circuits. Improvements have been made over OP07 specifications in several areas. Notable is bias current, which remains below 250 pA over the full military temperature range. The OP97 is ideal for use in precision long-term integrators or sample-andhold circuits that must operate at elevated temperatures. Common-mode rejection and power supply rejection are also improved with the OP97, at 114 dB minimum over wider ranges of common-mode or supply voltage. Outstanding PSR, a supply range specified from 2.25 V to 20 V and the OP97's minimal power requirements combine to make the OP97 a preferred device for portable and battery-powered instruments. The OP97 conforms to the OP07 pinout, with the null potentiometer connected between Pins 1 and 8 with the wiper to V+. The OP97 will upgrade circuit designs using 725, OP05, OP07, OP12, and 1012 type amplifiers. It may replace 741-type amplifiers in circuits without nulling or where the nulling circuitry has been removed.

NOTES 1 Absolute maximum ratings apply to both DICE and packaged parts, unless otherwise noted. 2 For supply voltages less than 20 V, the absolute maximum input voltage is equal to the supply voltage. 3 The OP97's inputs are protected by back-to-back diodes. Current-limiting resistors are not used in order to achieve low noise. Differential input voltages greater than 1 V will cause excessive current to flow through the input protection diodes unless limiting resistance is used. 4 JA is specified for worst case mounting conditions, i.e., JA is specified for device in socket for TO, cerdip, and P-DIP packages; JA is specified for device soldered to printed circuit board for SO package.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the OP97 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

OP97
APPLICATIONS INFORMATION
The OP97 is a low power alternative to the industry standard precision op amp, the OP07. The OP97 may be substituted directly into OP07, OP77, 725, 112/312, and 1012 sockets with improved performance and/or less power dissipation, and may be inserted into sockets conforming to the 741 pinout if nulling circuitry is not used. Generally, nulling circuitry used with earlier generation amplifiers is rendered superfluous by the OP97's extremely low offset voltage, and may be removed without compromising circuit performance. Extremely low bias current over the full military temperature range makes the OP97 attractive for use in sample-and-hold amplifiers, peak detectors, and log amplifiers that must operate over a wide temperature range. Balancing input resistances is not necessary with the OP97. Offset voltage and TCVOS are degraded only minimally by high source resistance, even when unbalanced. The input pins of the OP97 are protected against large differential voltage by back-to-back diodes. Current-limiting resistors are not used so that low noise performance is maintained. If differential voltages above 1 V are expected at the inputs, series resistors must be used to limit the current flow to a maximum of 10 mA. Common-mode voltages at the inputs are not restricted, and may vary over the full range of the supply voltages used. The OP97 requires very little operating headroom about the supply rails, and is specified for operation with supplies as low
+V RPOT = 5k TO 100k
as 2 V. Typically, the common-mode range extends to within one volt of either rail. The output typically swings to within one volt of the rails when using a 10 k load. Offset nulling is achieved utilizing the same circuitry as an OP07. A potentiometer between 5 k and 100 k is connected between pins 1 and 8 with the wiper connected to the positive supply. The trim range is between 300 V and 850 V, depending upon the internal trimming of the device.
AC PERFORMANCE
The OP97's ac characteristics are highly stable over its full operating temperature range. Unity-gain small-signal response is shown in Figure 2. Extremely tolerant of capacitive loading on the output, the OP97 displays excellent response even with 1000 pF loads (Figure 3). In large-signal applications, the input protection diodes effectively short the input to the output during the transients if the amplifier is connected in the usual unity-gain configuration. The output enters short-circuit current limit, with the flow going through the protection diodes. Improved large-signal transient response is obtained by using a feedback resistor between the output and the inverting input. Figure 4 shows the large-signal response of the OP97 in unity gain with a 10 k feedback resistor. The unity gain follower circuit is shown in Figure 5. The overcompensation pin may be used to increase the phase margin of the OP97, or to decrease gain-bandwidth product at gains greater than 10.

GUARDING AND SHIELDING
R4 10k
Figure 8. Current Monitor
To maintain the extremely high input impedances of the OP97, care must be taken in circuit board layout and manufacturing. Board surfaces must be kept scrupulously clean and free of moisture. Conformal coating is recommended to provide a humidity barrier. Even a clean PC board can have 100 pA of leakage currents between adjacent traces, so that guard rings should be used around the inputs. Guard traces are operated at a voltage close to that on the inputs, so that leakage currents become minimal. In noninverting applications, the guard ring should be connected to the common-mode voltage at the inverting input (Pin 2). In inverting applications, both inputs remain at ground, so that the guard trace should be grounded. Guard traces should be made on both sides of the circuit board.
High impedance circuitry is extremely susceptible to RF pickup, line frequency hum, and radiated noise from switching power supplies. Enclosing sensitive analog sections within grounded shields is generally necessary to prevent excessive noise pickup. Twisted-pair cable will aid in rejection of line frequency hum. The OP97 is an excellent choice as an output amplifier for higher resolution CMOS DACs. Its tightly trimmed offset voltage and minimal bias current result in virtually no degradation of linearity, even over wide temperature ranges. Figure 8 shows a versatile monitor circuit that can typically sense current at any point between the 15 V supplies. This makes it ideal for sensing current in applications such as full bridge drivers where bidirectional current is associated with large common-mode voltage changes. The 114 dB CMRR of the OP97 makes the amplifier's contribution to common-mode error negligible, leaving only the error due to the resistor ratio inequality. Ideally, R2/R4 = R3/R5. This is best trimmed via R4

The digitally programmable gain amplifier shown in Figure 10 has 12-bit gain resolution with 10-bit gain linearity over the range of -1 to -1024. The low bias current of the OP97 maintains this linearity, while C1 limits the noise voltage bandwidth allowing accurate measurement down to microvolt levels.

Figure 11. Combination High-Speed, Precision Amplifier
Many high-speed amplifiers suffer from less-than-perfect lowfrequency performance. A combination amplifier consisting of a high precision, slow device like the OP97 and a faster device such as the OP44 results in uniformly accurate performance from dc to the high frequency limit of the OP44, which has a gain-bandwidth product of 23 MHz. The circuit shown in Figure 11 accomplishes this, with the OP44 providing high frequency amplification and the OP97 operating on low frequency signals and providing offset correction. Offset voltage and drift of the circuit are controlled by the OP97.
