The SGM8431-1 is a single, rail-to-rail input and output, high voltage and high output drive CMOS operational amplifier. The device is optimized for high voltage operation from 4.5V to 36V single supply. It is capable of providing an output current of 400mAP-P (MIN). 

The SGM8431-1 is specifically designed for resolver excitation applications for motor driver, which require high voltage and high output current. In the application of resolver excitation, the SGM8431-1 is used to replace the complicated driver of resolver excitation, which is built with operational amplifiers and power transistors. 

The SGM8431-1 is available in a Green TO-252-5 package. It is specified over the extended -40℃ to +125℃ temperature range.
