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.
