GENERAL DEscriptION

The SGM8621/2/3/4 are a family of single, dual and quad operational amplifiers, which are optimized for low voltage, low noise and low power operation. These devices can operate from 2V to 5.5V single supply, while consuming low current. The supply current of SGM8623 is less than 1μA in power-down mode.

The SGM8621/2/3/4 feature a 3mV maximum input offset voltage. The minimum input common mode voltage is within 0.1V below the negative rail, and the output swing is rail-to-rail with heavy loads. They exhibit a high gain-bandwidth product of 3MHz and a slew rate of 1.7V/μs. These specifications make the operational amplifiers appropriate for various applications.

The SGM8621 is available in Green SC70-5, SOT-23-5 and SOIC-8 packages. The SGM8622 is available in Green SOIC-8 and MSOP-8 packages. The SGM8623 is available in Green SOT-23-6 and SOIC-8 packages. The SGM8624 is available in Green SOIC-14 and TSSOP-14 packages. They are specified over the extended industrial temperature range (-40℃ to +125℃).
