Description
AI
The LT1792 achieves a new standard of excellence in noise performance for a JFET op amp. The 4.2nV/√Hzvoltage noise combined with low current noise and picoampere bias currents make the LT1792 an ideal choice for amplifying low level signals from high impedance capacitive transducers.The LT1792 is unconditionally stable for gains of 1 or more, even with load capacitances up to 1000pF. Other key features are 600µV VOS and a voltage gain of over 4 million. Each individual amplifier is 100% tested for voltage noise, slew rate and gain bandwidth.The design of the LT1792 has been optimized to achieve true precision performance with an industry standard pinout in the SO-8 package. Specifications are also provided for ±5V supplies.ApplicationsPhotocurrent AmplifiersHydrophone AmplifiersHigh Sensitivity Piezoelectric AccelerometersLow Voltage and Current Noise Instrumentation Amplifier Front EndsTwo and Three Op Amp Instrumentation AmplifiersActive Filters
