LT6402-20
300MHz Low Distortion, Low

ADC Driver (A

DESCRIPTIO
The LT
廬
6402-20 is a low distortion, low noise differential
ampli鏗乪r/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 un鏗乴tered outputs
(+OUT and 鈥揙UT), the LT6402-20 has a built-in 75MHz
differential low pass 鏗乴ter and an additional pair of 鏗乴tered
outputs (+OUTFILTERED, 鈥揙UTFILTERED) to reduce
external 鏗乴tering components when driving high speed
ADCs. The output common mode voltage is easily set via
the V
OCM
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. It comes in a compact 16-lead 3mm
脳
3mm QFN pack-
age and operates over a 鈥?0擄C to 85擄C temperature range.
