OPA388QDBVRQ1

Texas Instruments · Precision OpAmps · SOT-23-5

OPA388QDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 output Amplifier output.
2 V- power_in Negative (lowest) power supply; single-supply 2.5 V to 5.5 V or dual-supply ±1.25 V to ±2.75 V operation across V+ and V-.
3 +IN input Noninverting input.
4 -IN input Inverting input.
5 V+ power_in Positive (highest) power supply; supply voltage VS = (V+) - (V-) is 2.5 V to 5.5 V recommended, with an absolute maximum of 6 V.
