The LTC6090HS8E#PBF is a high voltage precision monolithic Operational Amplifier for use with high voltage regulators. The LTC6090 is unity gain stable. The LTC6090-5 is stable in noise gain configurations of 5 or greater. Amplifier feature high open loop gain, low input referred offset voltage and noise, pA input bias current and ideal for high voltage, high impedance buffering and/or high gain configurations. The amplifier is internally protected against over-temperature conditions. A thermal warning output, TFLAG, goes active when the die temperature approaches 150°C. The output stage may be turned off with the output disable pin OD. By tying the OD pin to the thermal warning output (TFLAG), the part will disable the output stage when it is out of the safe operating area. These pins easily interface to any logic family. Amplifier may be run from a single 140V or spit ±70V power supplies and are capable of driving up to 200pF of load capacitance.
