| PIN | TYPE(1) | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| Ref | 1 | I | Reference input. This pin must be driven by a low impedance source. |
| VIN- | 2 | I | Negative (inverting) input |
| VIN+ | 3 | I | Positive (non-inverting) input |
| VS− | 4 | − | Negative supply |
| RG | 5 | I | Gain setting input. Place a resistor network between pin 1 and pin 5. |
| VO | 6 | O | Output of amplifier A2 |
| VS+ | 7 | − | Positive supply |
| VO1 | 8 | O | Output of amplifier A1 |
