OPA4182IDT

Texas Instruments · Precision Op Amps · SOIC-14

OPA4182IDT 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 channel A, which is rail-to-rail and can be continuously short-circuited to ground (one amplifier per package).
2 -IN A input Inverting input of amplifier channel A; the common-mode input range is (V-) - 0.1 V to (V+) - 2.5 V.
3 +IN A input Non-inverting input of amplifier channel A; the common-mode input range is (V-) - 0.1 V to (V+) - 2.5 V.
4 V+ power_in Positive power supply; single supply 4.5 V to 36 V or dual supply ±2.25 V to ±18 V, with absolute maximum 40 V single or ±20 V dual.
5 +IN B input Non-inverting input of amplifier channel B; the common-mode input range is (V-) - 0.1 V to (V+) - 2.5 V.
6 -IN B input Inverting input of amplifier channel B; the common-mode input range is (V-) - 0.1 V to (V+) - 2.5 V.
7 OUT B output Output of amplifier channel B, which is rail-to-rail and can be continuously short-circuited to ground (one amplifier per package).
8 OUT C output Output of amplifier channel C, which is rail-to-rail and can be continuously short-circuited to ground (one amplifier per package).
9 -IN C input Inverting input of amplifier channel C; the common-mode input range is (V-) - 0.1 V to (V+) - 2.5 V.
10 +IN C input Non-inverting input of amplifier channel C; the common-mode input range is (V-) - 0.1 V to (V+) - 2.5 V.
11 V- power_in Negative power supply; for dual supply it is the negative rail (down to -18 V), and for single supply it is the ground reference, with the input range extending to (V-) - 0.1 V.
12 +IN D input Non-inverting input of amplifier channel D; the common-mode input range is (V-) - 0.1 V to (V+) - 2.5 V.
13 -IN D input Inverting input of amplifier channel D; the common-mode input range is (V-) - 0.1 V to (V+) - 2.5 V.
14 OUT D output Output of amplifier channel D, which is rail-to-rail and can be continuously short-circuited to ground (one amplifier per package).
