General Description
nꢀ
40 MSPS converter
The CDK1305 is a 10-bit, low power analog-to-digital converter capable
of minimum word rates of 40 MSPS. The on-chip track-and-hold function
assures very good dynamic performance without the need for external

Power dissipation is extremely low at only 175mW typical at 40 MSPS with
a power supply of +5.0V. The digital outputs are +3V or +5V, and are user
selectable. The CDK1305 is pin-compatible with an entire family of 10-bit,
CMOS converters (CDK1304/05/06), which simplifies upgrades. The CDK1305
has incorporated proprietary circuit design* and CMOS processing
technologies to achieve its advanced performance. Inputs and outputs are
TTL/CMOS-compatible to interface with TTL/CMOS logic systems. Output
data format is straight binary.
