APX321WG-7

Diodes Incorporated · Operational Amplifier · SOT-25

APX321WG-7 from Diodes Incorporated, in a SOT-25. 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 IN+ input Non-inverting input with a common-mode range of 0 to V+ -0.2V (rail-to-rail input), and differential input voltage limited to ±supply voltage.
2 V- power_in Negative supply (ground in single-supply use, V- = 0V), with total supply V+ - V- of 2.5V to 5.5V.
3 IN- input Inverting input with a common-mode range of 0 to V+ -0.2V, and differential input voltage limited to ±supply voltage.
4 OUT output Rail-to-rail amplifier output swinging to within 10 mV of V+ and V- at 10 kΩ load; short circuit to either supply adversely affects reliability.
5 V+ power_in Positive supply, 2.5V to 5.5V relative to V- (absolute maximum 5.5V), with typical supply current of 110 µA.
