OPA4188AIDR from Texas Instruments, in a SOIC-14. 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 op-amp channel A. Rail-to-rail output stage; typical swing to within ~15 mV of supply rails at light load. Can drive 10 kΩ loads referenced to VS/2. |
| 2 | -IN A | input | Inverting input of op-amp channel A. High-impedance input (differential 100 MΩ |
| 3 | +IN A | input | Noninverting input of op-amp channel A. Common-mode input range extends from V− up to (V+) − 1.5 V; includes the negative supply rail. Input has integrated RFI filter. |
| 4 | V+ | power_in | Positive power-supply pin. Single-supply operation 4 V to 36 V, or dual supply ±2 V to ±18 V. Bypass with 0.1 µF ceramic close to the pin. Absolute maximum (V+)−(V−) = 40 V. |
| 5 | +IN B | input | Noninverting input of op-amp channel B. Common-mode input range extends from V− up to (V+) − 1.5 V; includes the negative supply rail. Input has integrated RFI filter. |
| 6 | -IN B | input | Inverting input of op-amp channel B. High-impedance input; input bias current ±160 pA typ, ±1400 pA max at 25 °C. |
| 7 | OUT B | output | Output of op-amp channel B. Rail-to-rail output; short-circuit protected (one amplifier at a time per package). |
| 8 | OUT C | output | Output of op-amp channel C. Rail-to-rail output; short-circuit protected (one amplifier at a time per package). |
| 9 | -IN C | input | Inverting input of op-amp channel C. High-impedance input; input bias current ±160 pA typ. |
| 10 | +IN C | input | Noninverting input of op-amp channel C. Common-mode range V− to (V+) − 1.5 V; includes negative rail. |
| 11 | V- | power_in | Negative power-supply pin. Tie to GND for single-supply operation, or to the negative rail for dual-supply operation (±2 V to ±18 V). Bypass with 0.1 µF ceramic close to the pin. |
| 12 | +IN D | input | Noninverting input of op-amp channel D. Common-mode range V− to (V+) − 1.5 V; includes negative rail. |
| 13 | -IN D | input | Inverting input of op-amp channel D. High-impedance input; input bias current ±160 pA typ. |
| 14 | OUT D | output | Output of op-amp channel D. Rail-to-rail output; short-circuit protected (one amplifier at a time per package). |
