DESCRIPTION

The TS97x family operational amplifiers is able to operate with voltages as low as ±1.35Vandfeaturing output Rail to Rail signal swing. The TS97x boasts characteristics that make them particularly well suited for portableandbattery-suppliedequipment. Very low noise and low distortion characteristics make them ideal for audio pre-amplification. The TS971 is housed in the space-saving 5 pins SOT23 package which simplifies theboard design because of the ability to be placed everywhere (outside dimensionsare 2.8mmx 2.9mm)

2. Differential voltages are non-inverting input terminal with respect to the inverting input terminal.

3. The magniture of input and output voltages mustnever exceed V

4. Short-circuits can cause excessive heatingand destructive dissipation.
