High Voltage Op Amp
Supply Voltage: +/-40V
Power Dissipation: 608mW
Differential Input Voltage: 80V
Input Voltage: +/-40V
Operating Temperature Range: -55°C to +125°C
The LM143 is a general purpose high voltage operational
amplifier featuring operation to g40V, complete input overvoltage
protection up to g40V and input currents comparable
to those of other super-b op amps. Increased slew rate,
together with higher common-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 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 environments
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.
