LT6402-20
300MHz Low Distortion, Low
Noise Differential Amplier/
ADC Driver (AV = 20dB)
The LT6402-20 is a low distortion, low noise differential
amplier/ADC driver for use in applications from DC to
300MHz. The LT6402-20 has been designed for ease of
use, with minimal support circuitry required. Exceptionally
low input-referred noise and low distortion (with either
single-ended or differential inputs) make the LT6402-20
an excellent solution for driving high speed 12-bit and
14-bit ADCs. In addition to the normal unltered outputs
(+OUT and –OUT), the LT6402-20 has a built-in 75MHz
differential low pass lter and an additional pair of ltered
outputs (+OUTFILTERED, –OUTFILTERED) to reduce
external ltering components when driving high speed
ADCs. The output common mode voltage is easily set via
the VOCM pin, eliminating an output transformer or AC-
coupling capacitors in many applications.
The LT6402-20 is designed to meet the demanding require-
ments of communications transceiver applications. It can
be used as a differential ADC driver, a general-purpose
differential gain block, or in other applications requiring
differential drive. The LT6402-20 can be used in data
acquisition systems required to function at frequencies
down to DC.
The LT6402-20 operates on a 5V supply and consumes
30mA.Itcomesinacompact16-lead3mm×3mmQFNpack-
