NCV321SN3T1G

onsemi · Operational Amplifier · TSOP-5

NCV321SN3T1G from onsemi, in a TSOP-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 +IN input Non-inverting analog input of the op-amp. Common-mode input range spans from V- - 0.2 V up to V+ + 0.2 V (rail-to-rail input); guaranteed 0 V to (V+ - 1 V) for CMRR ≥ 50 dB. Maximum input current 10 mA.
2 V- power_in Negative supply / ground reference. Typically tied to GND in single-supply operation. Supply span V+ to V- is 2.7 V to 5.5 V (absolute max).
3 -IN input Inverting analog input of the op-amp. Rail-to-rail input range identical to +IN; differential input voltage limited to ±V_S. Maximum input current 10 mA.
4 OUTPUT output Rail-to-rail push-pull output. Swings to within ~10 mV of either rail at 10 kΩ load. Output short-circuit current typically 60 mA sourcing / 160 mA sinking at V+ = 5 V; continuous short-circuit rated but sustained currents >45 mA can degrade reliability.
5 V+ power_in Positive supply. Operating range 2.7 V to 5.0 V (absolute max 5.5 V). Quiescent supply current I_CC typically 130 µA at V+ = 5 V.
