GT8021S5

GTIC · Operational Amplifier · SOT-23-5

GT8021S5 from GTIC, in a SOT-23-5. 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 output Amplifier output. Rail-to-rail output stage, swings within 30 mV of the supply rails; sources/sinks >100 mA typical.
2 V- power_in Negative (lowest) power supply. Ground in single-supply operation, or the negative rail (down to -2.75 V) in dual-supply operation. Supply span (V+)-(V-) must be 2.5 V to 5.5 V (abs max 6.5 V).
3 +IN input Non-inverting (positive) input. Common-mode range extends beyond the supplies (V- -0.3 V to V+ +0.5 V absolute max). CMOS gate: Ib ~ +/-1 pA typ.
4 -IN input Inverting (negative) input. CMOS gate: Ib ~ +/-1 pA typ, differential input impedance ~10^13 ohm
5 V+ power_in Positive (highest) power supply. +2.5 V to +5.5 V single-supply, or up to +2.75 V in dual-supply mode. Decouple with a 0.1 uF ceramic close to the pin.
