OPA2172IDGKR

Texas Instruments · Operational Amplifier · VSSOP-8

OPA2172IDGKR from Texas Instruments, in a VSSOP-8. 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 channel A; the datasheet specifies a continuous short-circuit to ground (one amplifier per package) as an absolute maximum condition.
2 -IN A input Inverting input of channel A; the input common-mode range extends 100 mV below V- and within 2 V of V+ for normal operation.
3 +IN A input Noninverting input of channel A; the input common-mode range extends 100 mV below V- and within 2 V of V+ for normal operation.
4 V- power_in Negative (lowest) power supply; the supply range is 4.5 V to 36 V total (±2.25 V to ±18 V) across V+ and V-.
5 +IN B input Noninverting input of channel B; the input common-mode range extends 100 mV below V- and within 2 V of V+ for normal operation.
6 -IN B input Inverting input of channel B; the input common-mode range extends 100 mV below V- and within 2 V of V+ for normal operation.
7 OUT B output Output of channel B; the datasheet specifies a continuous short-circuit to ground (one amplifier per package) as an absolute maximum condition.
8 V+ power_in Positive (highest) power supply; the supply range is 4.5 V to 36 V total (±2.25 V to ±18 V) across V+ and V-.
