OPA2141AIDR 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 | OUT A | output | Output of amplifier channel A. Rail-to-rail output, capable of sourcing +36mA and sinking -30mA (short-circuit typical). Swings to within 0.2V of the rails at RL=10kOhm. |
| 2 | -IN A | input | Inverting input of amplifier channel A. High-impedance JFET input (~10^13 Ohm |
| 3 | +IN A | input | Non-inverting input of amplifier channel A. High-impedance JFET input; common-mode range extends from (V-)-0.1V to (V+)-3.5V. |
| 4 | V- | power_in | Negative supply rail. Connect to GND for single-supply operation (4.5V to 36V total) or to a negative rail for dual-supply operation (+/-2.25V to +/-18V). |
| 5 | +IN B | input | Non-inverting input of amplifier channel B. High-impedance JFET input; common-mode range extends from (V-)-0.1V to (V+)-3.5V. |
| 6 | -IN B | input | Inverting input of amplifier channel B. High-impedance JFET input; 20pA max input bias current. |
| 7 | OUT B | output | Output of amplifier channel B. Rail-to-rail output, capable of sourcing +36mA and sinking -30mA (short-circuit typical). Swings to within 0.2V of the rails at RL=10kOhm. |
| 8 | V+ | power_in | Positive supply rail. 4.5V to 36V (single-supply) or +/-2.25V to +/-18V (dual-supply). Quiescent current 1.8mA typ, 2.3mA max per amplifier. |
