OPA4820IDR 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 | Output D | output | Output of amplifier channel D, which the datasheet rates for output current of ±85mA at VO = 0. |
| 2 | -Input D | input | Inverting input of channel D; the differential input voltage is limited to ±1.2V absolute maximum. |
| 3 | +Input D | input | Non-inverting input of channel D; the input common-mode voltage must stay within ±VS (absolute maximum). |
| 4 | +V | power_in | Negative power supply; the device operates from ±2V to ±6.3V dual supply, with a ±6.5V absolute maximum supply rating. |
| 5 | +Input C | input | Non-inverting input of channel C; the input common-mode voltage must stay within ±VS (absolute maximum). |
| 6 | -Input C | input | Inverting input of channel C; the differential input voltage is limited to ±1.2V absolute maximum. |
| 7 | Output C | output | Output of amplifier channel C, which the datasheet rates for output current of ±85mA at VO = 0. |
| 8 | Output B | output | Output of amplifier channel B, which the datasheet rates for output current of ±85mA at VO = 0. |
| 9 | -Input B | input | Inverting input of channel B; the differential input voltage is limited to ±1.2V absolute maximum. |
| 10 | +Input B | input | Non-inverting input of channel B; the input common-mode voltage must stay within ±VS (absolute maximum). |
| 11 | +V | power_in | Positive power supply; the device operates from ±2V to ±6.3V dual supply or +4V to +12.6V single supply, with a ±6.5V absolute maximum supply rating. |
| 12 | +Input A | input | Non-inverting input of channel A; the input common-mode voltage must stay within ±VS (absolute maximum). |
| 13 | -Input A | input | Inverting input of channel A; the differential input voltage is limited to ±1.2V absolute maximum. |
| 14 | Output A | output | Output of amplifier channel A, which the datasheet rates for output current of ±85mA at VO = 0. |
