LTC6090/LTC6090-5 140V CMOS Rail-to-Rail Output, Picoamp Input Current Op Amp
FEATURES DESCRIPTION
n
Supply Range: ±4.75V to ±70V (140V)
The LTC®6090/LTC6090-5 are high voltage, precision n
0.1Hz to 10Hz Noise: 3.5μVP-P
monolithic operational amplifiers. The LTC6090 is unity n
Input Bias Current: 50pA Maximum
gain stable. The LTC6090-5 is stable in noise gain con- n
Low Offset Voltage: 1.25mV Maximum
figurations of 5 or greater. Both amplifiers feature high n
Low Offset Drift: ±5µV/°C Maximum
open loop gain, low input referred offset voltage and noise, n
CMRR: 130dB Minimum
and pA input bias current and are ideal for high voltage, n Rail-to-Rail Output Stage high impedance buffering and/or high gain configurations. n Output Sink and Source: 50mA The amplifiers are internal y protected against over- n 12MHz Gain Bandwidth Product temperature conditions. A thermal warning output, TFLAG, n 21V/µs Slew Rate goes active when the die temperature approaches 150°C. n 11nV/√Hz Noise Density The output stage may be turned off with the output disable n Thermal Shutdown pin OD. By tying the OD pin to the thermal warning output n Available in Thermally Enhanced SOIC-8E or (TFLAG), the part will disable the output stage when it is TSSOP-16E Packages out of the safe operating area. These pins easily interface to any logic family.
APPLICATIONS
Both amplifiers may be run from a single 140V or spit n ±70V power supplies and are capable of driving up to ATE n 200pF of load capacitance. They are available in either an Piezo Drivers n 8-lead SO or 16-lead TSSOP package with exposed pad Photodiode Amplifier n for low thermal resistance.
