DESCRIPTION
2.4GHz Low Noise, Low
Distortion Differential ADC
Driver for 300MHz IF
The LTC6400-14 is a high-speed differential amplier
targeted at processing signals from DC to 300MHz. The
part has been specically 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 LTC6400-14 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 xed
at 14dB (5V/V).
The LTC6400-14 saves space and power compared to
alternative solutions using IF gain blocks and transformers.
The LTC6400-14 is packaged in a compact 16-lead 3mm
×
3mm QFN package and operates over the – 40°C to 85°C
temperature range.
