LM143 Datasheet | National Semiconductor

Description The LM143 is a general purpose high voltage operational amplifier featuring operation to g 40V plete input overvoltage protection up to g 40V and input currents parable to those of other super-b op amps Increased slew rate together with higher mon-mode and supply rejection insure improved performance at high supply voltages Operating characteristics in particular supply current slew rate and gain are virtually independent of supply voltage and temperature Furthermore gain is unaffected by output loading at high supply voltages due to thermal symmetry on the die The LM143 is pin patible with general purpose op amps and has offset null capability Application areas include those of general purpose op amps but can be extended to higher voltages and higher output power when externally boosted For example when used in audio power applications the LM143 provides a power bandwidth that covers the entire audio spectrum In addition the LM143 can be reliably operated in environments with large overvoltage spikes on the power supplies where other internally-pensated op amps would suffer catastrophic failure The LM343 is similar to the LM143 for applications in less severe supply voltage and temperature environments Features Y Y Y Y Y g 4 0V to g 40V Wide supply voltage range g 37V Large output voltage swing g 38V Wide input mon-mode range Input overvoltage protection Full g 40V Supply current is virtually independent of supply voltage and temperature Unique Characteristics Low input bias current 8 0 n A Low input offset current 1 0 n A High slew rate essentially independent of temperature and supply voltage 2 5V ms High voltage gain virtually independent of resistive loading temperature and supply voltage 100k min Internally pensated for unity gain Output short circuit protection Pin patible with general purpose op amps Connection Diagram Metal Can Package Top View TL H 7783 - 1 Order Number LM143H LM143H 883 or LM343H See NS Package Number...
