HIGH-VOLTAGE OPERATIONAL AMPLIFIER

DESCRIPTION

The SG143 is a general-purpose high-voltage operational amplifier featuring operation to ±40V and overvoltage protection up to ±40V. Increased slew rate, together with higher common-mode and supply rejection, insure improved performance at high supply voltages. Operating characteristics are independent of supply voltage and temperature. These devices are intended for use in high voltage applications where common-mode input ranges, high output voltage swings, and low input currents are required. Also, they are internally compensated and are pin compatible with industry standard operational amplifiers.
