The dual SGM8422 and quad SGM8424 are low power operational amplifiers optimized for high voltage systems. These devices can operate from 4.5V to 30V single supply or from ±2.25V to ±15V dual power supplies, and each amplifier consumes only 0.72mA quiescent current. They support rail-to-rail input and output operation, which results in wide dynamic range. The SGM8422/4 are suitable for low power systems, such as portable and battery-powered applications.
The SGM8422/4 have a gain-bandwidth product of 2.4MHz. They offer fast settling and slewing times. These devices are well suited for TFT-LCDs.
The SGM8422 is available in Green SOIC-8 and MSOP-8 packages. The SGM8424 is available in Green TSSOP-14 and SOIC-14 packages. They are specified over the extended -40℃ to +85℃ temperature range.
