PRODUCT 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 www.DataSheet4U.com be designed into a wide range of applications. The SGM8621/2/3/4 have a high gain-bandwidth product of 3MHz, a slew rate of 1.7V/µs, and a quiescent current of 250µA/amplifier at 5V. The SGM8623 has a power-down disable feature that reduces the supply current to 150nA. 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°C to +125°C). The operating range is from 2.5V to 5.5V. The single version, SGM8621/8623, is available in SC70-5, SO-8 and SOT23-5(6) packages. The dual version SGM8622 is available in SO-8 and MSOP-8 packages. The quad version SGM8624 is available in SO-16 and TSSOP-16 packages.
