| Order this document by LF441C/D Low Power JFET Input Operational Amplifiers These JFET input operational amplifiers are designed for low power applications. They feature high input impedance, low input bias current and low input offset current. Advanced design techniques allow for higher slew rates, gain bandwidth products and output swing. The LF441C device provides for the external null adjustment of input offset voltage. These devices are specified over the commercial temperature range. All are available in plastic dual in-line and SOIC packages. * Low Supply Current: 200 A/Amplifier LF441C LF442C LF444C LOW POWER JFET INPUT OPERATIONAL AMPLIFIERS SEMICONDUCTOR TECHNICAL DATA * * * * * * Low Input Bias Current: 5.0 pA High Gain Bandwidth: 2.0 MHz High Slew Rate: 6.0 V/s High Input Impedance: 1012 Large Output Voltage Swing: 14 V Output Short Circuit Protection 8 1 8 1 N SUFFIX PLASTIC PACKAGE CASE 626 D SUFFIX PLASTIC PACKAGE CASE 751 (SO-8) Representative Schematic Diagram (Each Amplifier) VCC PIN CONNECTIONS Offset Null Inputs VEE R4 Output Output 1 Inputs 1 1 2 8 1 2 3 4 8 - + 7 6 5 Q7 J1 Inputs + Q3 Q1 Q2 Q4 C1 C2 Q5 Q6 J2 D2 R3 D1 NC VCC Output Offset Null (Single, Top View) 1 2 - 3+ 4 7 VCC Output 2 Inputs 2 VEE - +5 6 (Dual, Top View) R1 R2 R5 VEE 5 * + 1 5 1.5 k VEE 100 k 14 1 1 1 * 14 *Null adjustment pins for LF441 only.

Differential voltages are at the noninverting input terminal with respect to the inverting input terminal. 2. The magnitude of the input voltage must never exceed the magnitude of the supply or 15 V, whichever is less. 3. Power dissipation must be considered to ensure maximum junction temperature (TJ) is not exceeded (see Figure 1).
