HTCSEMI HT277A
The HT277 is a dual low power CMOS operational amplifiers IC which provides high performance operation at low supply voltages. The basic amplifier can operate at supply voltage as low as 1.4V with very low power consumption and makes it perfect for battery-powered application. The input common-mode voltage extends to the negative rail.DESCRIPTION
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 operational amplifiers.FEATURES
