## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RGA | passive | Gain-setting resistor R1 connection; parasitic capacitance on this pin must be minimized and matched with pin 10 to maintain CMR and low gain error. |
| 2 | VINP | input | Noninverting input with an input voltage range of 0 V to 3.3 V at VCC = 5 V and 0 V to 0.15 V at VS = 1.8 V. |
| 3 | VCC | power_in | Positive supply pin operable from 1.8 V to 5.5 V, bypassed with a 0.1 µF surface-mount capacitor placed as close to the pin as possible. |
| 4 | VO | output | Rail-to-rail output buffer that can drive capacitive loads up to 100 pF. |
| 5 | VFB | passive | Provides access to the signal current at the output of the voltage-to-current converter, allowing the device to be used as a current-output amplifier. |
| 6 | ENABLE | input | Shutdown control that is connected to the positive supply for normal operation and to the negative supply to turn the device off, and must not be left floating. |
| 7 | VREF | power_in | Reference voltage input that sets the output reference level, with a specified VREF range of 0.8 V to 4.2 V. |
| 8 | GND | power_in | Ground reference pin for the device supply connections. |
| 9 | VINN | input | Inverting input; the differential input voltage is limited to ±VSUPPLY or ±5.0 V, whichever is less. |
| 10 | RGB | passive | Gain-setting resistor R1 connection; traces from this pin to R1 must be kept short and symmetric with pin 1 to avoid gain error. |
