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).
