## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RG | passive | Gain-setting pin; connect a resistor between pin 1 and pin 8 to set gain G = 1 + 49.4kΩ/RG (leave open for G = 1). |
| 2 | -IN | input | Inverting signal input; input voltage range is -VS + 0.1V to +VS - 2V, and a series resistor should limit current to 10mA for overvoltage. |
| 3 | +IN | input | Non-inverting signal input; input voltage range is -VS + 0.1V to +VS - 2V, and a series resistor should limit current to 10mA for overvoltage. |
| 4 | -VS | power_in | Negative power supply; split-supply operating range is ±2V to ±19V. |
| 5 | REF | input | Output reference voltage input that sets zero output level; connect to ground or a low-resistance source, with 40kΩ input resistance and range -VS to +VS. |
| 6 | OUTPUT | output | Amplifier output with short-circuit current of ±17mA and swing of within 0.2V of the supply rails (RL = 10kΩ). |
| 7 | +VS | power_in | Positive power supply; split-supply operating range is ±2V to ±19V, absolute maximum ±20V. |
| 8 | RG | passive | Gain-setting pin; connect a resistor between pin 8 and pin 1 to set gain G = 1 + 49.4kΩ/RG (leave open for G = 1). |
