High Voltage Operational Amplifier

The LM143 is a general purpose high voltage operational Amplifier featuring operation to g40V, complete input over- voltage protection up to g40V and input currents compara- ble 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. 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. By National Semiconductor Corporation
