The LT1169 achieves a new standard of excellence in noise

performance for a dual JFET op amp. For the first time low

voltage noise (6nV/ Hz) is simultaneously offered with

extremely low current noise (1fA/ Hz), providing the low-

est total noise for high impedance transducer applications.

Unlike most JFET op amps, the very low input bias current

(5pA Typ) is maintained over the entire common mode

range which results in an extremely high input resistance

(10

tance (1.5pF) an extremely high input impedance results,

making the LT1169 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 LT1169 is unconditionally stable for gains of 1 or more,

even with 1000pF capacitive loads. Other key features are

0.6mV V

vidual amplifier is 100% tested for voltage noise, slew rate

(4.2V/ s), and gain-bandwidth product (5.3MHz).

The LT1169 is offered in the S8 and N8 packages.

A full set of matching specifications are provided for

precision instrumentation amplifier front ends. Specifica-

tions at 5V supply operation are also provided. For an

even lower voltage noise please see the LT1113 data sheet.
