Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | −IN | input | Negative input summing node |
| 2 | VOCM | input | Voltage applied to this pin sets the common-mode output voltage with 1:1 ratio |
| 3 | V+ | power_in | Positive supply voltage |
| 4 | +OUT | output | Positive output; inverts voltage from the −IN input |
| 5 | −OUT | output | Negative output; inverts voltage from the +IN input |
| 6 | V− | power_in | Negative supply voltage |
| 7 | NC | unconnected | No connection |
| 8 | +IN | input | Positive input summing node |
