LTC6090, 140 V, CMOS, Rail-to-Rail Output, pA Input Current Op Amp

Analog Devices' LTC6090 / LTC6090-5 are high-voltage, precision, monolithic operational amplifiers. The LTC6090 is unity-gain stable. The LTC6090-5 is stable in noise-gain configurations of five or greater. Both amplifiers feature high open-loop gain, low input-referred offset voltage and noise, pA input bias current, and are ideal for high-voltage, high-impedance buffering and / or high-gain configurations.

The amplifiers are 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.

Both amplifiers may be run from a single 140 V or spit ±70 V power supplies and are capable of driving up to 200 pF of load capacitance. LTC6090 / LTC6090-5 are available in either an 8-lead SO or 16-lead TSSOP package with exposed pad for low thermal resistance.
