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: 3.5μVP-P
amplifier. The low noise, low bias current input stage is 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: ±5μV/°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 150°C. The n 12MHz Gain-Bandwidth Product output stage can be turned off with the output disable pin n 21V/μs 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 n High Voltage Regulators L, LT, LTC, LTM, Linear Technology, the Linear logo and Over-The-Top are registered trademarks of Linear Technology Corporation. All other trademarks are the property of their n Optical Networking respective owners.
