OPA4172AQPWRQ1

Texas Instruments · Operational Amplifier · TSSOP-14

OPA4172AQPWRQ1 from Texas Instruments, in a TSSOP-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; the datasheet states that a short-circuit to ground is continuous, one amplifier per package.
2 -IN A input Inverting input of amplifier channel A; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V.
3 +IN A input Non-inverting input of amplifier channel A; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V.
4 V+ power_in Positive (highest) power supply; single-supply operation is specified from 4.5 V to 36 V, and dual supply from ±2.25 V to ±18 V.
5 +IN B input Non-inverting input of amplifier channel B; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V.
6 -IN B input Inverting input of amplifier channel B; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V.
7 OUT B output Output of amplifier channel B; the datasheet states that a short-circuit to ground is continuous, one amplifier per package.
8 OUT C output Output of amplifier channel C; the datasheet states that a short-circuit to ground is continuous, one amplifier per package.
9 -IN C input Inverting input of amplifier channel C; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V.
10 +IN C input Non-inverting input of amplifier channel C; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V.
11 V- power_in Negative (lowest) power supply; for single-supply use this is the ground reference, and the input range extends 0.1 V below it.
12 +IN D input Non-inverting input of amplifier channel D; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V.
13 -IN D input Inverting input of amplifier channel D; the input common-mode range is (V-) - 0.1 V to (V+) - 2 V.
14 OUT D output Output of amplifier channel D; the datasheet states that a short-circuit to ground is continuous, one amplifier per package.
