OPA4131NJ from Texas Instruments, in a SOIC-14. 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; the datasheet rates the output short-circuit condition as continuous for one amplifier per package. |
| 2 | -IN A | input | Inverting input of channel A; input pins are diode-clamped to the supply rails, and input signals that swing more than 0.5 V beyond the rails must be current limited to 10 mA or less. |
| 3 | +IN A | input | Noninverting input of channel A; input pins are diode-clamped to the supply rails, and input signals that swing more than 0.5 V beyond the rails must be current limited to 10 mA or less. |
| 4 | V+ | power_in | Positive (highest) power supply; the recommended supply is ±4.5 V to ±18 V dual or 9 V to 36 V single. |
| 5 | +IN B | input | Noninverting input of channel B; input pins are diode-clamped to the supply rails, and input signals that swing more than 0.5 V beyond the rails must be current limited to 10 mA or less. |
| 6 | -IN B | input | Inverting input of channel B; input pins are diode-clamped to the supply rails, and input signals that swing more than 0.5 V beyond the rails must be current limited to 10 mA or less. |
| 7 | OUT B | output | Output of channel B; the datasheet rates the output short-circuit condition as continuous for one amplifier per package. |
| 8 | OUT C | output | Output of channel C; the datasheet rates the output short-circuit condition as continuous for one amplifier per package. |
| 9 | -IN C | input | Inverting input of channel C; input pins are diode-clamped to the supply rails, and input signals that swing more than 0.5 V beyond the rails must be current limited to 10 mA or less. |
| 10 | +IN C | input | Noninverting input of channel C; input pins are diode-clamped to the supply rails, and input signals that swing more than 0.5 V beyond the rails must be current limited to 10 mA or less. |
| 11 | V- | power_in | Negative (lowest) power supply, the return rail for the V+ supply span of ±4.5 V to ±18 V dual or 9 V to 36 V single. |
| 12 | +IN D | input | Noninverting input of channel D; input pins are diode-clamped to the supply rails, and input signals that swing more than 0.5 V beyond the rails must be current limited to 10 mA or less. |
| 13 | -IN D | input | Inverting input of channel D; input pins are diode-clamped to the supply rails, and input signals that swing more than 0.5 V beyond the rails must be current limited to 10 mA or less. |
| 14 | OUT D | output | Output of channel D; the datasheet rates the output short-circuit condition as continuous for one amplifier per package. |
