OPA2140AIDGKT 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 | Output of channel A, with rail-to-rail output voltage swing of (V-) + 0.2 to (V+) - 0.2 V with RL = 10 kΩ or (V-) + 0.35 to (V+) - 0.35 V with RL = 2 kΩ. |
| 2 | -IN A | input | Inverting input of channel A, with input voltage range of (V-) - 0.1 to (V+) - 3.5 V and maximum input current of ±10 mA. |
| 3 | +IN A | input | Noninverting input of channel A, with input voltage range of (V-) - 0.1 to (V+) - 3.5 V and maximum input current of ±10 mA. |
| 4 | V- | power_in | Negative (lowest) power supply voltage, with recommended operating range of 4.5 V to 36 V single supply or ±2.25 V to ±18 V dual supply. |
| 5 | +IN B | input | Noninverting input of channel B, with input voltage range of (V-) - 0.1 to (V+) - 3.5 V and maximum input current of ±10 mA. |
| 6 | -IN B | input | Inverting input of channel B, with input voltage range of (V-) - 0.1 to (V+) - 3.5 V and maximum input current of ±10 mA. |
| 7 | OUT B | output | Output of channel B, with rail-to-rail output voltage swing of (V-) + 0.2 to (V+) - 0.2 V with RL = 10 kΩ or (V-) + 0.35 to (V+) - 0.35 V with RL = 2 kΩ. |
| 8 | V+ | power_in | Positive (highest) power supply voltage, with recommended operating range of 4.5 V to 36 V single supply or ±2.25 V to ±18 V dual supply. |
