OPA2241UA

Texas Instruments · Operational Amplifier · SOIC-8

OPA2241UA from Texas Instruments, in a SOIC-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 Channel A output; rail-to-rail swing within 50mV of supply rails.
2 -IN A input Channel A inverting input; accepts common-mode signals from (V-) - 0.5V to (V+) + 0.5V.
3 +IN A input Channel A noninverting input; accepts common-mode signals from (V-) - 0.5V to (V+) + 0.5V.
4 V- power_in Negative power supply; 2.7V to 36V single-supply or ±1.35V to ±18V dual-supply referenced to V+.
5 +IN B input Channel B noninverting input; accepts common-mode signals from (V-) - 0.5V to (V+) + 0.5V.
6 -IN B input Channel B inverting input; accepts common-mode signals from (V-) - 0.5V to (V+) + 0.5V.
7 OUT B output Channel B output; rail-to-rail swing within 50mV of supply rails.
8 V+ power_in Positive power supply; 2.7V to 36V single-supply or ±1.35V to ±18V dual-supply referenced to V-.
