Introduction

AI Translation

The LT1793 achieves a new standard of excellence in noise performance for a JFET op amp. For the first time low voltage noise (6nV/√Hz) is simultaneously offered with extremely low current noise (0.8fA/√Hz), providing the lowest total noise for high impedance transducer applications. Unlike most JFET op amps, the very low input bias current (3pA typ) is maintained over the entire common mode range which results in an extremely high input resistance (10^13Ω). When combined with a very low input capacitance (1.5pF) an extremely high input impedance results, making the LT1793 the first choice for amplifying low level signals from high impedance transducers. The low input capacitance also assures high gain linearity when buffering AC signals from high impedance transducers. The LT1793 is unconditionally stable for gains of 1 or more, even with 1000pF capacitive loads. Other key features are 250μV and a voltage gain over 4 million. Each individual amplifier is 100% tested for voltage noise, slew rate (3.4V/μs) and gain - bandwidth product (4.2MHz). Specifications at ±5V supply operation are also provided. For an even lower voltage noise please see the LT1792 data sheet.
