DESCRIPTION
The single SGM8212-1Q and dual SGM8212-2Q 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 SGM8212-1Q and SGM8212-2Q also feature low offset voltage and high gain-bandwidth product.
These devices are AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and they are suitable for automotive applications.
The SGM8212-1Q is available in a Green SOT-23-5 package. The SGM8212-2Q is available in a Green SOIC-8 package. They are specified over the extended -40℃ to +125℃ temperature range.
