SGM8631

GENERAL DESCRIPTION

The SGM8631 (single), SGM8632 (dual) and SGM8633 (single with shutdown) are low noise, low voltage and low power operational amplifiers that can be designed into a wide range of applications. The SGM8631/2/3 have a high gain-bandwidth product of 6MHz and a slew rate of 3.7V/μs. The SGM8633 has a power-down disable feature that reduces the supply current to less than 1μA.

The SGM8631/2/3 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 3.5mV for SGM8631/2/3. They are specified over the extended industrial temperature range (-40 to +125). The operating supply range is from 2V to 5.5V.

The SGM8631 single is available in Green SC70-5, SOT-23-5 and SOIC-8 packages. The SGM8632 dual is available in Green SOIC-8 and MSOP-8 packages. The SGM8633 single with shutdown is available in Green SOT-23-6 and SOIC-8 packages.
