8-Bit, 275MSPS Analog-to-Digital Converter
Description
The Kenet KAD2708C is the industry’s lowest power,
8-bit, high performance Analog-to-Digital converter.
The converter runs at sampling rates up to 275MSPS,
and is fabricated with Kenet’s proprietary
FemtoCharge® CMOS technology. Users can now
obtain industry-leading SNR and SFDR specifications
while nearly halving power consumption. Sampling
rates of 210, 170 and 105MSPS are also available in
the same pin-compatible package and in versions
with 10-bit resolution. Kenet’s KAD2708L offers this
performance with LVDS outputs. All are available in
68-pin RoHS-compliant QFN packages with exposed
paddle. Performance is specified over the full
industrial temperature range (-40 to +85°C).
