OPA2188AIDR

Texas Instruments · Precision OpAmps · SOIC-8

OPA2188AIDR 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 op-amp output. Rail-to-rail output stage; drives up to ±18 mA short-circuit current with output swing to within ~250 mV of the rails at 10 kΩ load.
2 -IN A input Channel A inverting input. High-impedance CMOS input (100 MΩ
3 +IN A input Channel A non-inverting input. Common-mode range extends from V- to (V+)-1.5 V; input bias current ±160 pA typical.
4 V- power_in Negative supply rail. Connect to ground for single-supply operation or to the negative rail for split supply. Total supply range 4 V to 36 V (±2 V to ±18 V).
5 +IN B input Channel B non-inverting input. Common-mode range extends from V- to (V+)-1.5 V; input bias current ±160 pA typical.
6 -IN B input Channel B inverting input. High-impedance CMOS input (100 MΩ
7 OUT B output Channel B op-amp output. Rail-to-rail output stage; drives up to ±18 mA short-circuit current with output swing to within ~250 mV of the rails at 10 kΩ load.
8 V+ power_in Positive supply rail. Bypass with 100 nF close to the pin. Total supply range 4 V to 36 V (±2 V to ±18 V); quiescent current 475 µA maximum per amplifier.
