High Voltage Op Amp

National Semiconductor has just introduced two high voltage op amps, types LME49811 and LME49830. Operating with supply voltage up to 200V rail-to-rail, this supports a typical output voltage up to 192V, peak-to-peak. With a properly designed output stage, an output power up to 500W can be generated. While the op amp is aimed at audio applications, it can also be used for high voltage power supply and high voltage amplifier applications. These op amps might also serve as post-regulators or active ripple reducer circuits on a high voltage power supply.
