NCS333ASN2T1G

onsemi · Precision Op Amps · TSOT-23-5

NCS333ASN2T1G from onsemi, in a TSOT-23-5. 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 OUT output Amplifier output with rail-to-rail output swing; output short-circuit current is rated Continuous (short to ground) per the absolute maximum ratings.
2 VSS power_in Negative supply rail; supply is specified as VDD − VSS = 1.8 V to 5.5 V, and input voltages must stay above (VSS) − 0.3 V.
3 IN+ input Non-inverting input; input common-mode voltage range is VSS − 0.1 V to VDD + 0.1 V, and input current must be limited to 10 mA or less if the signal swings more than 0.3 V beyond the supply rails.
4 IN− input Inverting input; input common-mode voltage range is VSS − 0.1 V to VDD + 0.1 V, and input current must be limited to 10 mA or less if the signal swings more than 0.3 V beyond the supply rails.
5 VDD power_in Positive supply rail; supply is specified as VDD − VSS = 1.8 V to 5.5 V with an absolute maximum supply of 7 V.
