Description

The LTC®6091 is a dual, high voltage precision operational amplifier. The low noise, low bias current input stage is ideal for high gain configurations. The LTC6091 has low input offset voltage, a rail-to-rail output stage, and can be run from a single 140V or split ±70V supplies.

The LTC6091 is internally protected against overtemperture conditions. A thermal warning output, TFLAG, goes active when the die temperature approaches 150°C. The output stage can be turned off with the output disable pin OD. By tying the OD pin to the thermal warning output, the part will disable the output stage when it is out of the safe operating area. These pins easily interface to any logic family.

The LTC6091 is unity-gain stable with up to a 200pF output capacitor. A wide input and output common mode range along with many features makes the LTC6091 useful for many high voltage applications.
