## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BW | input | Bandwidth mode selection; connect to +VS for high bandwidth mode (gain-bandwidth ≥1 MHz) or to −VS for low bandwidth mode (200 kHz); do not leave floating. |
| 2 | +IN | input | Positive differential input; operating voltage range −VS − 0.3 V to +VS + 0.3 V at 25°C. |
| 3 | −IN | input | Negative differential input; operating voltage range −VS − 0.3 V to +VS + 0.3 V at 25°C. |
| 4 | −VS | power_in | Negative power supply; operating supply range 1.8 V to 5.5 V total supply voltage. |
| 5 | +VS | power_in | Positive power supply; operating supply range 1.8 V to 5.5 V total supply voltage. |
| 6 | REF | input | Reference input for output level shifting; operating voltage range −VS − 0.3 V to +VS + 0.3 V at 25°C. |
| 7 | FB | input | Feedback input for gain setting network; operating voltage range −VS − 0.3 V to +VS + 0.3 V at 25°C. |
| 8 | VOUT | output | Analog output; output voltage swing −VS + 0.05 V to +VS − 0.05 V at 25°C with 10 kΩ load to midsupply. |
