140V CMOS Op Amp with Rail-to-Rail Output & pA Inputs

September 01, 2015 // By Electronics EETimes

The LTC6090 high voltage CMOS op amp is the highest voltage monolithic op amp in the industry. It has a number of unique characteristics not found in other CMOS op amps. Unlike other CMOS amplifiers whose fine transistor geometries limit power supply operation to 5V, the LTC6090 is built on Linear Technology's proprietary 0.6 micron BiCMOS process, and can operate on supplies up to ±70V. Its CMOS inputs provide the ultimate in high voltage, high input impedance sensing
