General Description

The CDK1300 is a high-speed, 8-bit analog-to-digital converter implemented

in an advanced BiCMOS process. An advanced folding and interpolating

architecture provides both a high conversion rate and very low power

dissipation of only 310mW. The analog inputs can be operated in

either single-ended or differential input mode. A 2.5V common mode

reference is provided on chip for the single-ended input mode to minimize

external components.

The CDK1300 digital outputs are demuxed (double-wide) with both dual-

channel and single-channel selectable output modes. Demuxed mode

supports either parallel aligned or interleaved data output. The output logic

is both +3.0V and +5.0V compatible. The CDK1300 is available in a 44-lead

TQFP surface mount package over the industrial temperature range of -40°C

to +85°C.
