FEATURES

DESCRIPTION

The LTC^®6405 is a very low noise, low distortion, fully

differential input/output ampliﬁer optimized for 5V, single

supplyoperation.TheLTC6405inputcommonmoderange

is rail-to-rail, while the output common mode voltage is

independently adjustable by applying a voltage on the

Low Noise: 1.6nV/√Hz RTI

Low Power: 18mA at 5V

Low Distortion (HD2/HD3):

The output voltage swing extends from near-ground to

4V, to be compatible with a wide range of ADC converter

input requirements. The LTC6405 draws only 18mA, and

has a hardware shutdown feature which reduces current

consumption to 400μA.
