SG143
HIGH-VOLTAGE OPERATIONAL AMPLIFIER
DESCRIPTION
FEATURES
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.
• ±4.0V to ±40V supply voltage range
• ±37V output voltage swing
• ±24V common-mode voltages
• Overvoltage protection
• Output short circuit protection
HIGH RELIABILITY FEATURES-SG143
♦ Available to MIL-STD-883 and DESC SMD
♦ LMI level "S" processing available

THERMAL DATA
T Package:
Note A. Junction Temperature Calculation: TJ = TA + (PD x θJA).
Note B. The above numbers for θJC are maximums for the limiting
thermal resistance of the package in a standard mount-
ing configuration. The θJA numbers are meant to be
guidelines for the thermal performance of the device/pc-
board system. All of the above assume no ambient
airflow.
