PIN CONNECTIONS (top view) DESCRIPTION The TS912 is a RAIL TO RAIL CMOS dual operational amplifier designed to operate with a single or dual supply voltage. The input voltage range Vicm includes the two supply rails VCC+ and VCC-. The output reaches : * VCC- +40mV VCC+ -50mV with RL = 10k * VCC- +350mV VCC+ -350mV with RL = 600 This product offers a broad supply voltage operating range from 2.7V to 16V and a supply current of only 200A/amp. (VCC = 3V). Source and sink output current capability is typically 40mA (at VCC = 3V), fixed by an internal limitation circuit. STMicroelectronics is offering a quad op-amp with the same features : TS914.
