GENERAL DESCRIPTION

The single SGM8212-1 and dual SGM8212-2 are low

noise operational amplifiers optimized for high voltage

operation. These devices operate from 2.7V to 36V

single supply or ±1.35V to ±18V dual power supplies,

and consume low quiescent current. They provide

rail-to-rail input with a wide input common mode

voltage range from (-VS) - 0.1V to (+VS) + 0.1V, and

rail-to-rail output voltage swing. However, the

performance is reduced within 2V of the top rail.

The SGM8212-1/2 also feature low offset voltage and

high gain-bandwidth product.

The SGM8212-1 is available in Green SOT-553-5,

SOT-23-5 and SOIC-8 packages. The SGM8212-2 is

available in Green SOIC-8, MSOP-8 and TDFN-3×3-8L

packages. They are specified over the extended -40℃

to +125℃ temperature range.
