DESIGN IDEASвЂ‰L Dual ADC Driver with Tightly Matched
Gain and Phase Raises Quadrature
by Kris Lokere
Demodulation Performance
Introduction
High speed differential amplifiers help
to drive high performance analog-todigital converters (ADCs) by providing
balanced drive to the differential input
stage, setting the common mode level,
absorbing the sampling-energy, and
taking gain to reduce the output swing
requirement of preceding circuitry.
In applications involving multiple
ADCs, a compact, tightly matched
dual differential amplifier such as the
LTC6420-20 can further simplify the
design by reducing the uncertainty of
channel-to-channel variations.
The LTC6420-20 features two
1.8GHz differential amplifiers, each
capable of driving 12-, 14-and 16bit pipeline ADCs at low noise and
low distortion levels, even for input
frequencies as high as 300MHz. The …
