Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Ref | input | Output reference terminal; voltage applied to this pin is summed with output signal to refer the differential output voltage |
| 2 | -In | input | Negative differential input terminal with 50kΩ input impedance; operates within common-mode voltage range 2(V-)+5V to 2(V+)-5V |
| 3 | +In | input | Positive differential input terminal with 50kΩ input impedance; operates within common-mode voltage range 2(V-)+5V to 2(V+)-5V |
| 4 | V- | power_in | Negative power supply pin; supply voltage range ±4V to ±18V |
| 5 | NIC | unconnected | No Internal Connection; may be left open |
| 6 | Output | output | Difference amplifier output referenced to Ref pin (pin 1); output voltage range (V+)-2V to (V-)+2V, continuous current limit ±60mA |
| 7 | V+ | power_in | Positive power supply pin; supply voltage range ±4V to ±18V, quiescent current ±2.4mA |
| 8 | Sense | passive | Sense terminal for internal biasing and compensation; connection method not specified in typical applications |
