TSZ121IYLT

UMW · Precision Op Amps · SOT-23-5

TSZ121IYLT from UMW, in a SOT-23-5. 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 OUT output Op-amp output. Rail-to-rail output stage; typical VOH/VOL within 30 mV of the rails at 25 °C. Isink ~8 mA, Isource ~7 mA at VCC = 1.8 V.
2 VCC- power_in Negative supply / ground rail. Tie to GND in single-supply operation. Total supply range VCC+ − VCC- = 1.8 V to 5.5 V.
3 IN+ input Non-inverting input. Rail-to-rail common-mode range (VCC-) − 0.1 V to (VCC+) + 0.1 V. Very low input bias current (typ. 70 pA at VCC = 5 V).
4 IN- input Inverting input. Rail-to-rail common-mode range. Input current must be limited to 10 mA max by an external series resistor.
5 VCC+ power_in Positive supply. 1.8 V to 5.5 V operating (6 V absolute max). Decouple to VCC- with a local ceramic capacitor (e.g. 100 nF).
