SGM721 11MHz, Rail-to-Rail I/O CMOS Operational Amplifier


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.
