CDK1301
8-bit, 250 MSPS A/D Converter with Demuxed Outputs
General Description
The CDK1301 is a high-speed, 8-bit analog-to-digital converter implemented
in an advanced BiCMOS process. It is a performance-enhanced version of the
CDK1300, offering better linearity and dynamic performance. An advanced
folding and interpolating architecture provides both a high conversion
rate and very low power dissipation of only 425mW. 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 CDK1301 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 CDK1301 is available in a 44-lead TQFP surface
mount package over the industrial temperature range of -40°C to +85°C.
