ADA4940-1ARZ-R7 from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | −IN | input | Negative input summing node; input common-mode voltage range −VS − 0.2 V to +VS − 1.2 V. |
| 2 | VOCM | input | Output common-mode voltage control input with 250 kΩ input impedance for setting output common-mode level. |
| 3 | +VS | power_in | Positive supply voltage; operating range 3 V to 6 V for SOIC package. |
| 4 | +OUT | output | Positive differential output for load connection; voltage swing −VS + 0.1 V to +VS − 0.1 V. |
| 5 | −OUT | output | Negative differential output for load connection; voltage swing −VS + 0.1 V to +VS − 0.1 V. |
| 6 | −VS | power_in | Negative supply voltage and ground connection. |
| 7 | DISABLE | input | Disable pin for low power mode control; ≥ (−VS + 1.8) V enables amplifier, ≤ (−VS + 1) V disables to 7 µA to 28.5 µA quiescent current. |
| 8 | +IN | input | Positive input summing node; input common-mode voltage range −VS − 0.2 V to +VS − 1.2 V. |
