DESCRIPTION
2.2GHz Low Noise, Low
Distortion Differential ADC
Driver for DC-140MHz
The LTC6401-8 is a high-speed differential amplier tar-
geted at processing signals from DC to 140MHz. 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 LTC6401-8 is easy to use, with minimal support cir-
cuitry 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 8dB (2.5V/V).
The LTC6401-8 saves space and power compared to al-
ternative solutions using IF gain blocks and transformers.
The LTC6401-8 is packaged in a compact 16-lead 3mm ×
3mm QFN package and operates over the –40°C to 85°C
temperature range.
