The SGM721(single),SGM722(dual),SGM723(single with shutdown)and SGM724(quad)are low noise,low voltage and low power operational amplifiers,that can be designed into a wide range of applications.The SGM721/2/3/4 have a high gain-bandwidth product of 11MHz and a slew rate of 8.5V/μs.The SGM723 has a power-down disable feature that reduces the supply current to less than 1μA.

The SGM721/2/3/4 are designed to provide optimal performance in low voltage and low noise systems.They provide rail-to-rail output swing into heavy loads.The input common mode voltage range includes ground,and the maximum input offset voltage is 4mV for SGM721/2/3/4.They are specified over the extended industrial temperature range(-40℃to+125℃).The operating supply range is from 2.1V to 5.5V.

The single version,SGM721 is available in Green SC70-5,SOT-23-5 and SOIC-8 packages.SGM723 is available in Green SOT-23-6 and SOIC-8 packages.The dual version SGM722 is available in Green SOIC-8,MSOP-8 and TSSOP-8 packages.The quad version SGM724 is available in Green SOIC-14 and TSSOP-14 packages.
