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.

The LMx39x and the LM2901x devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.

The LM139 and LM139A devices are characterized for operation over the full military temperature range of –55°C to +125°C. The LM239 and LM239A devices are characterized for operation from –25°C to +85°C. The LM339 and LM339A devices are characterized for operation from 0°C to 70°C. The LM2901, LM2901AV, and LM2901V devices are characterized for operation from –40°C to +125°C.
