| 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.

Output Short Circuit Duration ............................................ 5 sec Operating Junction Temperature Hermetic (T, Y-Package) .............................................. 150C Storage Temperature Range ............................ -65C to 150C Lead Temperature (Soldering, 10 Seconds) ................... 300C THERMAL DATA T Package: Thermal Resistance-Junction to Case, JC ................... 25C/W Thermal Resistance-Junction to Ambient, JA ............ 130C/W Y Package: Thermal Resistance-Junction to Case, JC .................. 50C/W Thermal Resistance-Junction to Ambient, JA ........... 130C/W Note A. Junction Temperature Calculation: TJ = TA + (PD x JA). Note B. The above numbers for JC are maximums for the limiting thermal resistance of the package in a standard mounting configuration. The JA numbers are meant to be guidelines for the thermal performance of the device/pcboard system. All of the above assume no ambient airflow.
