KAD2708L
FN6813.0
8-Bit, 350/275/210/170/105MSPS A/D
Converter
The Intersil KAD2708L is the industry’s lowest power, 8-bit,
350MSPS, high performance Analog-to-Digital converter. It is
designed with Intersil’s proprietary FemtoCharge™ technology
on a standard CMOS process. The KAD2708L offers high
dynamic performance (48.8dBFS SNR @ f_IN = 175MHz) while
consuming less than 330mW. Features include an over-range
indicator and a selectable divide-by-2 input clock divider. The
KAD2708L 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 Ld RoHS-compliant
QFN packages with exposed paddle. Performance is specified
over the full industrial temperature range (-40°C to +85°C).

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination finish,
which is RoHS compliant and compatible with both SnPb and Pb-free
soldering operations). Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
