8 Pins
Pinout Table8
| Pin | Signal / Name | Type | Alternative Functions |
|---|---|---|---|
| 1 | NULL | Analog | Offset Null Pin 1 — connect 10kΩ pot between pins 1 and 5 with wiper to V- to null input offset voltage; leave NC if offset nulling not required |
| 2 | INA- | Analog | Inverting Input (-) — output swings negative when this input rises above IN+ |
| 3 | INA+ | Analog | Non-Inverting Input (+) — output swings positive when this input rises above IN- |
| 4 | V- | Ground | Negative Supply Voltage (typically -15V for bipolar ±15V operation; add 100nF bypass cap to V+) |
| 5 | NULL | Analog | Offset Null Pin 2 — see pin 1; connect 10kΩ pot wiper to V-, with ends at pins 1 and 5 |
| 6 | OUT A | Analog | Amplifier Output — swings to within ~2V of each supply rail; short-circuit protected; drives up to ±25mA |
| 7 | V+ | Power | Positive Supply Voltage (typically +15V for bipolar ±15V operation; ±5V to ±18V range; add 100nF bypass cap to V-) |
| 8 | NC | NC | - |
