OPA141AIDGKR from Texas Instruments, in a VSSOP-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; this pin may be left floating or tied to any potential within the supply rails without affecting device operation. |
| 2 | -IN | input | Inverting input of the JFET-input amplifier; input bias current is ±2pA typical/±20pA max, and the common-mode voltage range extends from (V-)-0.1V to (V+)-3.5V. |
| 3 | +IN | input | Non-inverting input of the JFET-input amplifier; input bias current is ±2pA typical/±20pA max, and the common-mode voltage range extends from (V-)-0.1V to (V+)-3.5V. |
| 4 | V- | power_in | Negative supply pin; specified operating range is ±2.25V to ±18V for dual supplies (or 4.5V to 36V single supply), with an absolute maximum total supply voltage of ±20V. |
| 5 | NC | unconnected | No internal connection; this pin may be left floating or tied to any potential within the supply rails without affecting device operation. |
| 6 | OUT | output | Amplifier output; provides rail-to-rail swing to within 0.2V of either supply rail into a 10kΩ load, with short-circuit current limited to +36mA sourcing/-30mA sinking. |
| 7 | V+ | power_in | Positive supply pin; specified operating range is ±2.25V to ±18V for dual supplies (or 4.5V to 36V single supply), with an absolute maximum total supply voltage of ±20V. |
| 8 | NC | unconnected | No internal connection; this pin may be left floating or tied to any potential within the supply rails without affecting device operation. |
