Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connection; labeled NC in the OPA1677 D (SOIC-8) top view and not listed in the pin function table. |
| 2 | -IN | input | Inverting input; the input voltage must stay between (V-) - 0.5 V and (V+) + 0.5 V and input current is limited to ±10 mA per the absolute maximum ratings. |
| 3 | +IN | input | Noninverting input; the input voltage must stay between (V-) - 0.5 V and (V+) + 0.5 V and input current is limited to ±10 mA per the absolute maximum ratings. |
| 4 | V- | power_in | Negative (lowest) power supply; the device runs from 4.5 V to 36 V single supply or ±2.25 V to ±18 V dual supply, with total supply VS = (V+) - (V-) not to exceed 40 V. |
| 5 | NC | unconnected | No connection; labeled NC in the OPA1677 D (SOIC-8) top view and not listed in the pin function table. |
| 6 | OUT | output | Amplifier output, which may be shorted to VS/2 (ground in symmetrical dual-supply setups) with continuous short-circuit current per the absolute maximum ratings. |
| 7 | V+ | power_in | Positive (highest) power supply; the device runs from 4.5 V to 36 V single supply or ±2.25 V to ±18 V dual supply, with total supply VS = (V+) - (V-) not to exceed 40 V. |
| 8 | NC | unconnected | No connection; labeled NC in the OPA1677 D (SOIC-8) top view and not listed in the pin function table. |
