DESCRIPTION
The TS912 is a RAIL TO RAIL dual CMOS opera-
tional amplifier designed to operate with single or
dual supply voltage.
The input voltage range Vicm includes the two
supplyrails VCC+and VCC-.
The outputreaches :
•VCC-+50mV VCC+-50mV with RL= 10kΩ
•VCC-+650mV VCC+-650mV with RL= 600Ω
This product offers a broad supply voltageoperat-
ing range from2.7Vto 16V,a supplycurrent ofonly
400µA/amp (VCC = 10V) and a high output current
capability fixed by an internal limitation circuit :
Isource =65mA- Isink = 75mA
