description
The LT1013 devices are dual precision operational amplifiers, featuring high gain, low supply current, low noise, and low-offset-voltage temperature coefficient. The LT1013 devices can be operated from a single 5-V power supply; the common-mode input voltage range includes ground, and the output can also swing to within a few millivolts of ground. Crossover distortion is eliminated. The LT1013 can be operated with both dual 15-V and single 5-V supplies.

The LT1013C and LT1013AC, and LT1013D are characterized for operation from 0C to 70C. The LT1013I and LT1013AI, and LT1013DI are characterized for operation from -40C to 105C. The LT1013M and LT1013AM, and LT1013DM are characterized for operation over the full military temperature range of -55C to 125C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC-. 2. Differential voltages are at IN+ with respect to IN-. 3. The output may be shorted to either supply. 4. The package thermal impedance is calculated in accordance with JESD 51-7.

SLOS018E - MAY 1988 - REVISED SEPTEMBER 2001
APPLICATION INFORMATION single-supply operation
The LT1013 is fully specified for single-supply operation (VCC- = 0). The common-mode input voltage range includes ground, and the output swings to within a few millivolts of ground. Furthermore, the LT1013 has specific circuitry that addresses the difficulties of single-supply operation, both at the input and at the output. At the input, the driving signal can fall below 0 V, either inadvertently or on a transient basis. If the input is more than a few hundred millivolts below ground, the LT1013 is designed to deal with the following two problems that can occur: 1. On many other operational amplifiers, when the input is more than a diode drop below ground, unlimited current flows from the substrate (VCC- terminal) to the input, which can destroy the unit. On the LT1013, the 400- resistors in series with the input [see schematic (each amplifier)] protect the device, even when the input is 5 V below ground. 2. When the input is more than 400 mV below ground (at TA = 25C), the input stage of similar type operational amplifiers saturates and phase reversal occurs at the output. This can cause lockup in servo systems. Because of a unique phase-reversal protection circuitry (Q21, Q22, Q27, and Q28), the LT1013 outputs do not reverse, even when the inputs are at -1.5 V (see Figure 24). This phase-reversal protection circuitry does not function when the other operational amplifier on the LT1013 is driven hard into negative saturation at the output. Phase-reversal protection does not work on amplifier 1 when amplifier 2 output is in negative saturation nor on amplifier 2 when amplifier 1 output is in negative saturation. At the output, other single-supply designs either cannot swing to within 600 mV of ground or cannot sink more than a few microamperes while swinging to ground. The all-npn output stage of the LT1013 maintains its low output resistance and high-gain characteristics until the output is saturated. In dual-supply operations, the output stage is free of crossover distortion.

APPLICATION INFORMATION comparator applications
The single-supply operation of the LT1013 lends itself for use as a precision comparator with TTL-compatible output. In systems using both operational amplifiers and comparators, the LT1013 can perform multiple duties (see Figures 25 and 26).

low-supply operation
The minimum supply voltage for proper operation of the LT1013 is 3.4 V (three NiCad batteries). Typical supply current at this voltage is 290 A; therefore, power dissipation is only 1 mW per amplifier.
offset voltage and noise testing
The test circuit for measuring input offset voltage and its temperature coefficient is shown in Figure 30. This circuit, with supply voltages increased to 20 V, also is used as the burn-in configuration. The peak-to-peak equivalent input noise voltage of the LT1013 is measured using the test circuit shown in Figure 27. The frequency response of the noise tester indicates that the 0.1-Hz corner is defined by only one zero. The test time to measure 0.1-Hz to 10-Hz noise should not exceed 10 seconds, as this time limit acts as an additional zero to eliminate noise contribution from the frequency band below 0.1 Hz. An input noise voltage test is recommended when measuring the noise of a large number of units. A 10-Hz input noise voltage measurement correlates well with a 0.1-Hz peak-to-peak noise reading because both results are determined by the white noise and the location of the 1/f corner frequency. Current noise is measured by the circuit and formula shown in Figure 28. The noise of the source resistors is subtracted.
