OPA2991IPWR

Texas Instruments · Operational Amplifier · TSSOP-8

OPA2991IPWR from Texas Instruments, in a TSSOP-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.
2 -IN A input Inverting input of channel A; differential input range extends to the full 40-V supply span.
3 +IN A input Noninverting input of channel A; common-mode range extends 100 mV beyond either supply rail.
4 V- power_in Negative (lowest) supply; total supply (V+)-(V-) rated 2.7 V to 40 V.
5 +IN B input Noninverting input of channel B; common-mode range extends 100 mV beyond either supply rail.
6 -IN B input Inverting input of channel B; differential input range extends to the full 40-V supply span.
7 OUT B output Output of channel B.
8 V+ power_in Positive (highest) supply; total supply (V+)-(V-) rated 2.7 V to 40 V, with a 0.1 µF bypass capacitor recommended nearby.
