Dual Channel Amplifier
General Description
Utilizing the circuit designs perfected for recently introduced Quad Operational Amplifiers, these dual operational
amplifiers have several distinct advantages over standard operational amplifier types in single supply applications. They
can operate at supply voltages as low as 3.0 Volts or as high as 26 Volts with quiescent currents about one fifth of those
associated with the LM741 (on a pet amplifier basis). The common mode input range includes the negative supply,
thereby eliminating the necessity for external biasing components in many applications.
The TS2904 is equivalent to one half of TS2902, and output voltage range also includes the negative supply voltage.
The TS2904 is offered in 8 pin SOP-8 and DIP-8 package.

NOTE :
1. Split Power Supplies.
2. For supply. Voltages less than 26V for the TS2904 the absolute maximum input voltage is equal to the supply voltage.
3. This input current will only exist when the voltage is negative at any of the input leads. Normal output states will
reestablish when the input voltage returns to a voltage greater than -0.3V.
