OPA4188AIDR

Texas Instruments · Precision OpAmps · SOIC-14

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).
