DESCRIPTION
The TS912 is a RAIL TO RAIL CMOS dual operational amplifier designed to operate with single or
dual supply voltage.
The input voltage range Vicm includes the two
supply rails VCC+ and VCC-.
The output reaches :
• VCC- +50mV
VCC+ -50mV
with RL = 10kΩ
• VCC- +650mV VCC+ -650mV with RL = 600Ω
This product offers a broad supply voltage operating range from 2.7V to 16V, a supply current of only
400µA/amp (VCC = 10V) and a high output current
capability fixed by an internal limitation circuit :
Isource = 65mA - Isink = 75mA
SGS-THOMSON is offering a quad op-amp with
the same features : TS914.

2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of input and output voltages must never exceed VCC+ +0.3V.
