16V

■ Extremely low input bias current: 1pA typ.

■ Low input offset voltage: 2mV max.

■ Specified for 600Ω and 100Ω loads

■ Low supply current: 200μA/ampli

(VCC = 3V)

■ Latch-up immunity

■ ESD tolerance: 3kV

■ Spice macromodel included in this specification

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- +30mV, VCC+ -40mV, with RL = 10kΩ

■ VCC- +300mV, VCC+ -400mV, with RL = 600Ω

This product offers a broad supply voltage

operating range from 2.7V to 16V and 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.
