KAD2710L
10-Bit, 275/210/170/105MSPS A/D
Converter
The KAD2710L is the industry’s lowest power, 10-bit,
275MSPS, high performance Analog-to-Digital converter. It
is designed with Intersil’s proprietary FemtoCharge™
technology on a standard CMOS process. The KAD2710L
offers high dynamic performance (55.6dBFS SNR @
f
IN
= 138MHz) while consuming less than 280mW. Features
include an over-range indicator and a selectable divide-by-2
input clock divider. The KAD2710L is one member of a
pin-compatible family offering 8 and 10-bit ADCs with
sample rates from 105MSPS to 350MSPS and
LVDS-compatible or LVCMOS outputs (Table 1). This family
of products is available in 68-pin RoHS-compliant QFN
packages with exposed paddle. Performance is specified
over the full industrial temperature range (-40°c to +85°C).
