| 4 | OUT+ | output | Positive output pin of the fully differential output pair. |
| 5 | OUT- | output | Negative output pin of the fully differential output pair. |
| 6 | VCC- | power_in | Negative supply voltage pin; VCC- to VCC+ is rated to a 37 V absolute maximum supply. |
| 7 | NC | unconnected | Not internally connected; leave floating or connect to any other pin on the device. |
| 8 | IN+ | input | Positive input pin; the differential input voltage is rated to ±1.5 V (absolute maximum) and continuous input current to 10 mA. |
