SGM8422 2.4MHz, High Voltage, Rail-to-Rail I/O Operational Amplifier


The SGM8422 (dual) and SGM8424 (quad) are low power, high voltage, rail-to-rail input and output operational amplifiers. These devices can operate from ±2.25V to ±15V dual power supplies or from +4.5V to +30V single supplies.

The SGM8422/4 have a gain-bandwidth product of 2.4MHz (TYP), while consuming only 0.72mA per amplifier. They also provide common mode input ability beyond the supply rails, as well as rail-to-rail output capability. This enables the SGM8422/4 to offer maximum dynamic range at any supply voltage.

The SGM8422/4 also feature fast slewing and settling times. These features make these amplifiers ideal for use as voltage reference buffers in Thin Film Transistor Liquid Crystal Displays (TFT-LCD). Other applications include battery power, portable devices, and anywhere low power consumption is important.

The SGM8422 comes in Green SOIC-8 and MSOP-8 packages. The SGM8424 is offered in Green TSSOP-14 and SOIC-14 packages. They are specified over the extended -40 to +85 temperature range.
