GENERAL DEscriptION

The SGM8425 (single), SGM8426 (dual) and SGM8428 (quad) 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 1.6mA current. They support rail-to-rail input and output operation, which results in wide dynamic range. The SGM8425/6/8 are suitable for low power systems, such as portable and battery-powered applications.

The SGM8425/6/8 have a bandwidth of 18MHz at -3dB. They offer fast settling and slewing times. These devices are well suited for TFT-LCDs.

The SGM8425 is available in Green SOT-23-5, SOIC-8 and MSOP-8 packages. The SGM8426 is available in Green SOIC-8 and MSOP-8 packages. The SGM8428 is available in Green TSSOP-14 and SOIC-14 packages. They are rated over the -40℃ to +85℃ temperature range.
