OPA2141AIDGKR from Texas Instruments, in a MSOP-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 | OUT A | output | Channel A output, rail-to-rail swing to within (V-)+0.2V and (V+)-0.2V with RL = 10kΩ, with continuous short-circuit protection (source +36mA, sink -30mA). |
| 2 | -IN A | input | Channel A inverting input, diode-clamped to the supply rails with signals beyond 0.5V outside the rails to be current limited to 10mA or less. |
| 3 | +IN A | input | Channel A non-inverting input, diode-clamped to the supply rails with input range including V- and signals beyond 0.5V outside the rails to be current limited to 10mA or less. |
| 4 | V- | power_in | Negative supply (ground in single-supply use), with specified total supply range of 4.5V to 36V (±2.25V to ±18V). |
| 5 | +IN B | input | Channel B non-inverting input, diode-clamped to the supply rails with input range including V- and signals beyond 0.5V outside the rails to be current limited to 10mA or less. |
| 6 | -IN B | input | Channel B inverting input, diode-clamped to the supply rails with signals beyond 0.5V outside the rails to be current limited to 10mA or less. |
| 7 | OUT B | output | Channel B output, rail-to-rail swing to within (V-)+0.2V and (V+)-0.2V with RL = 10kΩ, with continuous short-circuit protection (source +36mA, sink -30mA). |
| 8 | V+ | power_in | Positive supply, with specified total supply range of 4.5V to 36V (±2.25V to ±18V) and absolute maximum supply voltage of ±20V. |
