Pinout

Pin Name Type Function
1 NULL passive Offset-null terminal for the PDIP package, used with a 20 kΩ potentiometer per Figure 46 to trim input offset; the datasheet notes that offset adjustment changes offset drift by 4 μV/°C for every millivolt of induced offset.
2 -IN input Inverting input of the N-channel JFET input stage, where the minimum common-mode range extends 0.2 V below -VS and the input current flows out of the terminal during normal operation.
3 +IN input Noninverting input whose common-mode range extends to 1 V below +VS, and which should have a series resistor (for example 1 kΩ) if the input may exceed +VS by more than 300 mV.
4 -VS power_in Negative supply rail, which is ground in single-supply operation; the part operates from single supplies of 5 V to 30 V or dual supplies of ±2.5 V to ±15 V (features) with an absolute maximum supply of ±18 V.
5 NULL passive Second offset-null terminal of the PDIP package, used together with pin 1 for external offset trimming per Figure 46; the null pins are not functional in the SOIC or MSOP packages.
6 VOUT output Output that swings within 10 mV of the positive rail and 5 mV of the negative rail with no load, sources and sinks a minimum of 15 mA, and drives up to 350 pF of direct capacitive load.
7 +VS power_in Positive supply rail, with single-supply operation from 5 V to 30 V (features) or 5 V to 36 V (general description) and an absolute maximum supply of ±18 V.
8 NC unconnected No connect pin, which is not internally connected on the 8-Lead PDIP package.
