LT1792

Low Noise, Precision,

JFET Input Op Amp

FEATURES

DESCRIPTIO

100% Tested Low Voltage Noise: 6nV/√Hz Max

A Grade 100% Temperature Tested

Voltage Gain: 1.2 Million Min

Offset Voltage Over Temp: 800µV Max

Gain-Bandwidth Product: 5.6MHz Typ

Guaranteed Specifications with

±5V

Supplies

The LT

1792 achieves a new standard of excellence in

noise performance for a JFET op amp. The 4.2nV/√Hz

voltage 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 V

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 pro-

vided for

±5V

supplies.
