OPA694IDR from Texas Instruments, 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 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net; not electrically connected to the die. |
| 2 | Inverting Input | input | Inverting input of the current-feedback op-amp. Typical inverting input bias current ±2µA; inverting input impedance ~30Ω (open-loop). Connect the feedback resistor R_F (nominally 402Ω) between this pin and the Output pin. |
| 3 | Noninverting Input | input | Noninverting (+) input of the current-feedback op-amp. Typical noninverting input bias current ±5µA; input impedance 280kΩ |
| 4 | -Vs | power_in | Negative supply rail. Typical operating supply ±5V; absolute maximum ±6.5V. Bypass with local decoupling capacitors close to the pin. |
| 5 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net. |
| 6 | Output | output | Op-amp output. Delivers ±80mA typical output current with ±3.4V output swing into 100Ω load on ±5V supplies. Short-circuit current ±200mA typical. |
| 7 | +Vs | power_in | Positive supply rail. Typical operating supply ±5V; absolute maximum ±6.5V. Bypass with local decoupling capacitors close to the pin. |
| 8 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net. |
