Texas Instruments · Precision Op Amps · VSSOP-8

OPA2188AIDGKR from Texas Instruments, in a VSSOP-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; the output limits into the appropriate supply rail when the input is driven beyond its common-mode range (phase-reversal protection, page 18).
2 -IN A input Negative (inverting) input signal for channel A.
3 +IN A input Positive (noninverting) input signal for channel A; the input common-mode range includes the negative supply rail (V-).
4 V- power_in Negative (lowest) power supply; the device operates from 4 V to 36 V total supply (±2 V to ±18 V) per the recommended operating conditions.
5 +IN B input Positive (noninverting) input signal for channel B; the input common-mode range includes the negative supply rail (V-).
6 -IN B input Negative (inverting) input signal for channel B.
7 OUT B output Output of channel B; the output limits into the appropriate supply rail when the input is driven beyond its common-mode range (phase-reversal protection, page 18).
8 V+ power_in Positive (highest) power supply; the device operates from 4 V to 36 V total supply (±2 V to ±18 V) per the recommended operating conditions.
