PIN CONNECTIONS (top view) DESCRIPTION The TS3V912 is a RAIL TO RAIL CMOS dual operational amplifier designed to operate with a single 3V supply voltage.
The input voltage range Vicm includes the two supply rails VCC+ and VCC-.
The output reaches : • VCC- +40mV VCC+ -50mV with RL = 10kΩ • VCC- +350mV VCC+ -350mV with RL = 600Ω This product offers a broad supply voltage operating range from 2.
7V to 16V and a supply current of only 200µA/amp.
(VCC = 3V).
Source and sink output current capability is typically 40mA (at VCC = 3V), fixed by an internal limitation circuit.
SGS-THOMSON is offering a quad op-amp with the same features : TS3V914.
