OPA2188AQDGKRQ1

Texas Instruments · Precision Op Amps · VSSOP-8

OPA2188AQDGKRQ1 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 Channel A output; the output is rail-to-rail and swings within 15 mV of the supply rails, and it can be shorted continuously to ground, V- or V+.
2 -IN A input Channel A inverting input; input signal current must be limited to 10 mA or less when the input can exceed a supply rail by more than 0.5 V, and the common-mode range extends from V- to (V+) - 1.5 V.
3 +IN A input Channel A non-inverting input; input signal current must be limited to 10 mA or less when the input can exceed a supply rail by more than 0.5 V, and the common-mode range extends from V- to (V+) - 1.5 V.
4 V- power_in Negative power supply (lowest potential); the recommended operating range is 4 V to 36 V single-supply or ±2 V to ±18 V dual-supply, and the absolute maximum is 40 V single-supply or ±20 V dual-supply.
5 +IN B input Channel B non-inverting input; input signal current must be limited to 10 mA or less when the input can exceed a supply rail by more than 0.5 V, and the common-mode range extends from V- to (V+) - 1.5 V.
6 -IN B input Channel B inverting input; input signal current must be limited to 10 mA or less when the input can exceed a supply rail by more than 0.5 V, and the common-mode range extends from V- to (V+) - 1.5 V.
7 OUT B output Channel B output; the output is rail-to-rail and swings within 15 mV of the supply rails, and it can be shorted continuously to ground, V- or V+.
8 V+ power_in Positive power supply (highest potential); the recommended operating range is 4 V to 36 V single-supply or ±2 V to ±18 V dual-supply, and the absolute maximum is 40 V single-supply or ±20 V dual-supply.
