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

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).
