Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | V+ | power_in | Power supply voltage, tied internally to pin 4, specified for 4.5V to 5.5V operation (not tested below 4.5V). |
| 2 | +IN | input | Positive sense input pin, with common mode range of -5V to 80V. |
| 3 | -IN | input | Negative sense input pin, with common mode range of -5V to 80V. |
| 4 | V+ | power_in | Power supply voltage, tied internally to pin 1, specified for 4.5V to 5.5V operation (not tested below 4.5V). |
| 5 | GND | power_in | Ground pin. |
| 6 | REF | input | Reference pin input that sets the output common mode level, defaulting to mid-supply via two 160k resistors and overdrivable by an external source able to drive 80k. |
| 7 | OUT | output | Voltage output, VOUT = AV*(VSENSE ± VOSI), drives up to 200pF directly; use at least 100 ohm series resistor for larger capacitive loads. |
| 8 | SHDN | input | Shutdown pin that places the part in low power shutdown when pulled within 0.5V of GND, with an internal 2µA pull-up selecting active state when floating. |
