OPA2140AIDR

Texas Instruments · FET Input Amplifiers · SOIC-8

OPA2140AIDR 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 Channel A output; swings (V- + 0.35) to (V+ - 0.35) V with 2 kΩ load.
2 -IN A input Channel A inverting input; common-mode range (V- - 0.1) to (V+ - 3.5) V.
3 +IN A input Channel A noninverting input; common-mode range (V- - 0.1) to (V+ - 3.5) V.
4 V- power_in Negative (lowest) power supply; recommended range ±2.25 V to ±18 V dual supply or 4.5 V to 36 V single supply.
5 +IN B input Channel B noninverting input; common-mode range (V- - 0.1) to (V+ - 3.5) V.
6 -IN B input Channel B inverting input; common-mode range (V- - 0.1) to (V+ - 3.5) V.
7 OUT B output Channel B output; swings (V- + 0.35) to (V+ - 0.35) V with 2 kΩ load.
8 V+ power_in Positive (highest) power supply; recommended range ±2.25 V to ±18 V dual supply or 4.5 V to 36 V single supply.
