OP1177ARMZ-R7 from Analog Devices, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connect; the datasheet marks this pin NC = no connect and gives no function for it. |
| 2 | -IN | input | Inverting input; common-mode input range is ±3.5 V at ±5 V supplies and ±13.5 V at ±15 V supplies, and the internal protection tolerates voltages up to 2.5 V beyond either supply. |
| 3 | +IN | input | Noninverting input; common-mode input range is ±3.5 V at ±5 V supplies and ±13.5 V at ±15 V supplies, and the internal protection tolerates voltages up to 2.5 V beyond either supply. |
| 4 | V- | power_in | Negative supply; the amplifier operates from dual supplies of ±2.5 V to ±15 V. |
| 5 | NC | unconnected | No connect; the datasheet marks this pin NC = no connect and gives no function for it. |
| 6 | OUT | output | Amplifier output; sources or sinks up to ±10 mA with dropout below 1.2 V and is stable with capacitive loads up to 1000 pF. |
| 7 | V+ | power_in | Positive supply; the amplifier operates from dual supplies of ±2.5 V to ±15 V, with a 36 V absolute maximum supply voltage. |
| 8 | NC | unconnected | No connect; the datasheet marks this pin NC = no connect and gives no function for it. |
