TSZ121ICT

STMicroelectronics · Precision Op Amps · SC-70-5

TSZ121ICT from STMicroelectronics, in a SC-70-5. 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 input of the operational amplifier, part of the rail-to-rail input stage with common mode range extended to (VCC-)-0.1V to (VCC+)+0.1V.
2 VCC- power_in Negative supply rail (ground in single-supply operation); supply voltage range is 1.8 V to 5.5 V between VCC+ and VCC-.
3 IN- input Inverting input of the operational amplifier, part of the rail-to-rail input stage with common mode range extended to (VCC-)-0.1V to (VCC+)+0.1V.
4 OUT output Rail-to-rail amplifier output, capable of swinging to within 30 mV (typ.) of either supply rail when loaded with 10 kOhm to VCC/2.
5 VCC+ power_in Positive supply pin; operating supply voltage range is 1.8 V to 5.5 V, with maximum supply voltage of 6 V (absolute maximum).
