ADA4922-1ARDZ from Analog Devices, in a SOIC-8-EP. 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 | NIC | unconnected | No internal connection. |
| 2 | REF | input | Reference voltage for the single-ended input signal; it sets the output baseline of the inverting path (OUT−) and is normally tied to the input signal midswing level (often midsupply, or ground for bipolar signals and supplies). |
| 3 | VS+ | power_in | Positive power supply; total supply operating range is 5 V to 26 V, with broadband decoupling placed as close as possible to the pin. |
| 4 | OUT+ | output | Noninverting side of the differential output, which follows the input voltage (VOUT+ = VIN) and can swing ±10.7 V typical on ±12 V supplies. |
| 5 | OUT− | output | Inverting side of the differential output (VOUT− = −VIN + 2(REF)), which can swing ±10.7 V typical on ±12 V supplies. |
| 6 | VS− | power_in | Negative power supply; total supply operating range is 5 V to 26 V, with broadband decoupling placed as close as possible to the pin. |
| 7 | DIS | input | Disable input, active low; on ±12 V supplies disabled at ≤ −11 V and enabled at ≥ −9 V, and the outputs are not placed in a high-impedance state when disabled. |
| 8 | IN | input | Single-ended signal input with 11 MΩ input resistance and an input voltage range of ±10.7 V on ±12 V supplies. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
