SGM8622 3MHz, Rail-to-Rail I/O CMOS Operational Amplifier

GENERAL DESCRIPTION

The SGM8621 (single), SGM8622 (dual), SGM8623 (single with shutdown) and SGM8624 (quad) are low noise, low voltage, and low power operational amplifiers, that can be designed into a wide range of applications. The SGM8621/2/3/4 have a high gain-bandwidth product of 3MHz and a slew rate of 1.7V/μs. The SGM8623 has a power-down disable feature that reduces the supply current to less than 1μA.

The SGM8621/2/3/4 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 3mV for SGM8621/2/3/4. They are specified over the extended industrial temperature range (-40 to +125). The operating supply range is from 2V to 5.5V.

The single version, SGM8621 is available in Green SC70-5, SOT-23-5 and SOIC-8 packages. SGM8623 is available in Green SOT-23-6 and SOIC-8 packages. The dual version SGM8622 is available in Green SOIC-8 and MSOP-8 packages. The quad version SGM8624 is available in Green SOIC-14 and TSSOP-14 packages.
