OPA323IDCKR

TI(德州仪器) · Operational Amplifier · SC-70-5

OPA323IDCKR from TI(德州仪器), 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 Noninverting input of the single-channel OPA323 amplifier.
2 V- power_in Negative (low) supply or ground, used for single-supply operation; the recommended supply span (V+) - (V-) is 1.7V to 5.5V.
3 IN- input Inverting input of the single-channel OPA323 amplifier.
4 OUT output Amplifier output, which has a rail-to-rail output stage.
5 V+ power_in Positive (high) supply pin; the recommended supply span (V+) - (V-) is 1.7V to 5.5V.
