DESCRIPTION

The WT272C/WT274C is a dual/quad low power CMOS operational amplifiers IC. It provides high performance operation at low supply voltages. The basic amplifier can operate at supply voltage as low as 1.2V with very low power consumption and makes it perfect for battery-powered application. The input common-mode voltage extends to the negative rail. The output swings to both rails with light load. The input bias current is inherently low and the input impedance is extremely high. The devices are ideal upgrades for industrial standards OP amp.
