OPA2156IDR

Texas Instruments · Precision OpAmps · SOIC-8

OPA2156IDR from Texas Instruments, in a SOIC-8. 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, channel A. Rail-to-rail output stage capable of sourcing/sinking up to 100 mA.
2 -IN A input Inverting input, channel A. Rail-to-rail input, common-mode range from (V-)-0.1 V to (V+)+0.1 V.
3 +IN A input Noninverting input, channel A. Rail-to-rail CMOS input with ±5 pA typical bias current.
4 V- power_in Negative (lowest) power supply. Total supply (V+)-(V-) range is 4.5 V to 36 V (±2.25 V to ±18 V).
5 +IN B input Noninverting input, channel B. Rail-to-rail CMOS input with ±5 pA typical bias current.
6 -IN B input Inverting input, channel B. Rail-to-rail input, common-mode range from (V-)-0.1 V to (V+)+0.1 V.
7 OUT B output Output, channel B. Rail-to-rail output stage capable of sourcing/sinking up to 100 mA.
8 V+ power_in Positive (highest) power supply. Total supply (V+)-(V-) range is 4.5 V to 36 V (±2.25 V to ±18 V), or up to 40 V single-supply.
