TS321
Low Power Single Operational Amplifier
SOT-25
Pin Definition:
1. Input +
2. Ground
3. Input -
4. Output
5. Vcc
General Description
The TS321 brings performance and economy to low power systems. With high unity gain frequency and a guaranteed
0.4V/uS slew rate, the quiescent current is only 430uA/amplifier (5V). The input common mode range includes ground
and therefore the device is able to operate in single supply applications as well as in dual supply applications. It is also
capable of comfortably driving large capacitive loads.
The TS321 is available in the SOT-25 package. Overall the TS321 is a low power, wide supply range performance OP
Amp that can be designed into a wide range of applications at an economical price without sacrificing valuable board
space.

2. short circuits from the output V+ can cause excessive heating and eventual destruction. When considering short
circuits to ground the maximum output current is approximately 40mA independent of the magnitude of V+ values of
supply voltage in excess of +15v,continuous short circuit can exceed the power dissipation ratings and cause
eventual destruction.
