GT8531S5

GTIC · Precision OpAmps · SOT-23-5

GT8531S5 from GTIC, 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, rail-to-rail output swing per the datasheet.
2 V- power_in Negative (lowest) power supply; single-supply operation spans 1.8 V to 5.5 V across V+ and V-.
3 +IN input Positive (noninverting) input; common-mode range is (V-) -0.1 V to (V+) +0.1 V.
4 -IN input Negative (inverting) input; common-mode range is (V-) -0.1 V to (V+) +0.1 V.
5 V+ power_in Positive (highest) power supply; supply voltage Vs=(V+)-(V-) must not exceed the 6.5 V absolute maximum.
