General Description

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

components. The input drive requirements are minimized due to the CDK1305

low input capacitance of only 5pF.

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.

The CDK1305 is available in 28-lead SOIC and 32-lead small (7mm square)

TQFP packages over the commercial temperature range.
