LM143 LM343 High Voltage

Operational Amplifier

General Description

The LM143 is a general purpose high voltage operational

amplifier featuring operation to

voltage protection up to

ble to those of other super- op amps Increased slew rate

together with higher common-mode and supply rejection

insure improved performance at high supply voltages Oper-

ating 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 compatible 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 environ-

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
