DESCRIPTION
Dual Matched
1.3GHz Differential
Ampliers/ADC Drivers
The LTC6421-20 is a dual high speed differential amplier
targeted 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 LTC6421-20 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
capacitors in many applications. The gain is internally
xed at 20dB (10V/ V).
The LTC6421-20 saves space and power compared to
alternative solutions using IF gain blocks and transformers.
The LTC6421-20 is packaged in a compact 20-lead
3mm × 4mm QFN package and operates over the – 40°C
to 85°C temperature range.
