DESCRIPTION
1.3GHz Low Noise, Low
Distortion Differential ADC
Driver for 140MHz IF
The LTC
6401-20 is a high-speed differential amplifier
targeted at processing signals from DC to 140MHz. The
part has been specifically designed to drive 12-, 14- and
16-bit ADCs with low noise and low distortion, but can also
be used as a general-purpose broadband gain block.
The LTC6401-20 is easy to use, with minimal support
circuitry required. The output common mode voltage is
set using an external pin, independent of the inputs, which
eliminates the need for transformers or AC-coupling ca-
pacitors in many applications. The gain is internally fixed
at 20dB (10V/V).
The LTC6401-20 saves space and power compared to
alternative solutions using IF gain blocks and transform-
ers. The LTC6401-20 is packaged in a compact 16-lead
3mm
×
3mm QFN package and operates over the –40°C
to 85°C temperature range.
