SG143
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.
