OPA4137U 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 amplifier A, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V. |
| 2 | -In A | input | Inverting input of amplifier A; input current should be limited to 2mA when the input exceeds the supply rails. |
| 3 | +In A | input | Non-inverting input of amplifier A; common-mode range runs from (V-)+3V to (V+). |
| 4 | V+ | power_in | Positive supply, 4.5V to 36V single-supply (±2.25V to ±18V dual), bypassed with a 10nF or larger ceramic capacitor. |
| 5 | +In B | input | Non-inverting input of amplifier B; common-mode range runs from (V-)+3V to (V+). |
| 6 | -In B | input | Inverting input of amplifier B; input current should be limited to 2mA when the input exceeds the supply rails. |
| 7 | Out B | output | Output of amplifier B, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V. |
| 8 | Out C | output | Output of amplifier C, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V. |
| 9 | -In C | input | Inverting input of amplifier C; input current should be limited to 2mA when the input exceeds the supply rails. |
| 10 | +In C | input | Non-inverting input of amplifier C; common-mode range runs from (V-)+3V to (V+). |
| 11 | V- | power_in | Negative supply or ground in single-supply use; total supply (V+ to V-) is 4.5V to 36V (±2.25V to ±18V). |
| 12 | +In D | input | Non-inverting input of amplifier D; common-mode range runs from (V-)+3V to (V+). |
| 13 | -In D | input | Inverting input of amplifier D; input current should be limited to 2mA when the input exceeds the supply rails. |
| 14 | Out D | output | Output of amplifier D, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V. |
