SG1536
High-Voltage Operational Amplifier
Description
Features
The SG1536 series of monolithic amplifiers is designed
specifically for use in high voltage applications up to ±40 V
and where high common-mode input ranges, high output
voltage swings, and low input currents are required. These
devices are internally compensated and are pin compatible
with industry standard operational amplifiers.
