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.
