OA1ZHA22C

STMicroelectronics · Precision Op Amps · SC-70-5

OA1ZHA22C from STMicroelectronics, in a SC-70-5. 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 IN+ input Non-inverting input; rail-to-rail common-mode range of (VCC-) - 0.1 V to (VCC+) + 0.1 V, with input current limited to 10 mA by a series resistor.
2 VCC- power_in Negative supply voltage (ground in single-supply use); supply range VCC is 1.8 V to 5.5 V.
3 IN- input Inverting input; rail-to-rail common-mode range of (VCC-) - 0.1 V to (VCC+) + 0.1 V, with input current limited to 10 mA by a series resistor.
4 OUT output Rail-to-rail amplifier output swinging to within 30 mV of either rail at 25 °C with a 10 kΩ load to VCC/2.
5 VCC+ power_in Positive supply voltage of 1.8 V to 5.5 V (6 V absolute maximum); a 0.1 µF decoupling capacitor close to the supply pins is recommended.
