KAD2708C
FN6812.1
8-Bit, 275/210/170/105MSPS A/D Converter
The KAD2708C is the industry’s lowest power, 8-bit,
275MSPS, high performance Analog-to-Digital converter. It
is designed with Intersil’s proprietary FemtoCharge™
technology on a standard CMOS process. The KAD2708C
offers high dynamic performance (49.2dBFS SNR @
f_IN = 138MHz) while consuming less than 265mW. Features
include an over-range indicator and a selectable divide-by-2
input clock divider. The KAD2708C is one member of a
pin-compatible family offering 8 and 10-bit ADCs with
sample rates from 105MSPS to 350MSPS and LVCMOS or
LVDS-compatible 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).

NOTES:
1. 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.
2. For Moisture Sensitivity Level (MSL), please see device information
page for KAD2708C-10, KAD2708C-17, KAD2708C-21 and
KAD2708C-27. For more information on MSL please see techbrief
TB363.
