LM143 LM343 High Voltage Operational Amplifier February 1995 LM143 LM343 High Voltage Operational Amplifier General Description Features The LM143 is a general purpose high voltage operational Y Wide supply voltage range g 4 0V to g 40V amplifier featuring operation to g 40V complete input over- Y Large output voltage swing g 37V voltage protection up to g 40V and input currents compara- Y Wide input common-mode range g 38V ble to those of other super-b op amps Increased slew rate Y Input overvoltage protection Full g 40V together with higher common-mode and supply rejection Y Supply current is virtually independent of supply voltage insure improved performance at high supply voltages Oper- and temperature ating characteristics in particular supply current slew rate and gain are virtually independent of supply voltage and temperature Furthermore gain is unaffected by output Unique Characteristics loading at high supply voltages due to thermal symmetry on Y Low input bias current 8 0 nA the die The LM143 is pin compatible with general purpose Y Low input offset current 1 0 nA op amps and has offset null capability Y High slew rate essentially independent of temperature Application areas include those of general purpose op and supply voltage 2 5V ms amps but can be extended to higher voltages and higher Y High voltage gain virtually independent of resistive output power when externally boosted For example when loading temperature and supply voltage 100k min used in audio power applications the LM143 provides a Y Internally compensated for unity gain power bandwidth that covers the entire audio spectrum In Y Output short circuit protection addition the LM143 can be reliably operated in environ- Y Pin compatible with general purpose op amps ments with large overvoltage spikes on the power supplies where other internally-compensated op amps would suffer catastrophic failure The LM343 is similar to the LM143 for applications in less severe supply voltage and temperature environments Connection Diagram Metal Can Package Top View
