DIO20721ST5

DIOO · Operational Amplifier · SOT-23-5

DIO20721ST5 from DIOO, 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; typical output current 85mA at V+=5V (20-27mA at V+=2.5V) with closed-loop output impedance ~2.8Ω at 1MHz.
2 V- power_in Negative supply / ground reference. Tie to GND for single-supply operation. Supply range (V+ - V-) is 2.5V to 5.5V (absolute max 7V).
3 +IN input Non-inverting input. Rail-to-rail common-mode range from (V-)-0.1V to (V+)+0.1V. Input bias current ~1pA.
4 -IN input Inverting input. Rail-to-rail common-mode range from (V-)-0.1V to (V+)+0.1V. Input offset voltage 0.5mV typical (±5mV max over -40 to 125°C).
5 V+ power_in Positive supply. 2.5V to 5.5V recommended (absolute max 7V). Decouple close to the pin. PSRR is 110dB typical.
