10-Bit, 275MSPS Analog-to-Digital Converter
Description
The Kenet KAD2710L is the industry’s lowest power,
10-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 8-bit
resolution. Kenet’s KAD2710C offers this
performance with LVCMOS 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).
Key Specifications
