The LT

1793 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 applica-

tions. 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 resis-

tance (10

Ω).

When combined with a very low input ca-

pacitance (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 V

and a voltage gain over 4 million. Each indi-

vidual 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.
