SGM721/SGM722/SGM723/SGM724 11MHz, Rail-to-Rail I/O CMOS Operational Amplifiers GENERAL DESCRIPTION The SGM721/2/3/4 are a family of single, dual and quad operational amplifiers, which are optimized for low voltage, low noise and low power operation. These devices can operate from 2.1V to 5.5V single supply, and consume low quiescent current. The supply current of SGM723 is less than 1μA in power-down mode. The SGM721/2/3/4 feature a 4mV maximum input offset voltage. The minimum input common mode voltage is within 0.1V below the negative rail, and the output swing is rail-to-rail with heavy loads. They exhibit a high gain-bandwidth product of 11MHz and a slew rate of 8.5V/μs. These specifications make the operational amplifiers appropriate for various applications.
