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 be designed into a wide range of applications. The SGM8621/2/3/4 have a high gain-bandwidth productof 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.
