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.
