140V CMOS Rail-to-Rail

Output, Picoamp Input

Current Op Amp

The LTC®6090/LTC6090-5 are high voltage, precision

monolithic operational amplifiers. The LTC6090 is unity

gain stable. The LTC6090-5 is stable in noise gain con-

figurations of 5 or greater. Both amplifiers feature high

openloopgain,lowinputreferredoffsetvoltageandnoise,

and pA input bias current and are ideal for high voltage,

highimpedancebufferingand/orhighgainconfigurations.

The amplifiers are internally protected against over-

temperatureconditions.Athermalwarningoutput,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 140V or spit

±70V power supplies and are capable of driving up to

200pF of load capacitance. They are available in either an

8-lead SO or 16-lead TSSOP package with exposed pad

for low thermal resistance.
