ADA4627-1ARZ-R7 from Analog Devices, in a SOIC-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 | NULL | passive | Offset null pin for the SOIC package; with a 100 kΩ potentiometer the adjustment range is more than ±11 mV, but the datasheet recommends not using these pins because VOS drift increases by several µV/°C per millivolt of adjustment. |
| 2 | -IN | input | Inverting input; the device is not rail-to-rail, so this input must stay within the input voltage range of −11 V to +11 V (−10.5 V to +10.5 V over −40°C to +125°C) at ±15 V supplies. |
| 3 | +IN | input | Noninverting input; the device is not rail-to-rail, so this input must stay within the input voltage range of −11 V to +11 V (−10.5 V to +10.5 V over −40°C to +125°C) at ±15 V supplies, and input current must be limited to 10 mA when the input exceeds the supply rail by 0.3 V. |
| 4 | V- | power_in | Negative supply pin; the device operates from ±5 V to ±15 V dual supply, and the datasheet recommends connecting the exposed pad to V- on the LFCSP variant. |
| 5 | NULL | passive | Offset null pin for the SOIC package; with a 100 kΩ potentiometer the adjustment range is more than ±11 mV, but the datasheet recommends not using these pins because VOS drift increases by several µV/°C per millivolt of adjustment. |
| 6 | OUT | output | Amplifier output; at ±15 V supplies with RL = 1 kΩ it swings typically 12.0 V high and −12.7 V low, and output current is ±45 mA at VO = ±10 V. |
| 7 | V+ | power_in | Positive supply pin; the device operates from ±5 V to ±15 V dual supply, with a 36 V absolute maximum supply voltage. |
| 8 | NC | unconnected | No connect; the datasheet marks this pin NC and it is not internally connected. |
