LTC6091 Dual 140V, Rail-to-Rail Output, Picoamp Input Current Op Amp FEATURES DESCRIPTION n Supply Range: 4.75V to 70V (140V) The LTC 6091 is a dual, high voltage precision operational n 0.1Hz to 10Hz Noise: 3.5V amplifier. The low noise, low bias current input stage is P-P n Input Bias Current: 50pA Maximum ideal for high gain configurations. The LTC6091 has low n Low Offset Voltage: 1.25mV Maximum input offset voltage, a rail-to-rail output stage, and can be n Low Offset Drift: 5V/C Maximum run from a single 140V or split 70V supplies. n CMRR: 130dB Minimum The LTC6091 is internally protected against overtemper- n Rail-to-Rail Output Stage ture conditions. A thermal warning output, TFLAG, goes n Output Sink and Source: 50mA active when the die temperature approaches 150C. The n 12MHz Gain-Bandwidth Product output stage can be turned off with the output disable pin n 21V/s Slew Rate OD. By tying the OD pin to the thermal warning output, n 11nV/Hz Noise Density the part will disable the output stage when it is out of the n Thermal Shutdown safe operating area. These pins easily interface to any n 4mm 6mm 16-Lead QFN Package logic family. APPLICATIONS The LTC6091 is unity-gain stable with up to a 200pF output capacitor. A wide input and output common mode range n ATE along with many features makes the LTC6091 useful for n Piezo Drivers many high voltage applications. n Photodiode Amplifier L, LT, LTC, LTM, Linear Technology, the Linear logo and Over-The-Top are registered n High Voltage Regulators trademarks of Linear Technology Corporation.
