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
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).
