General Description
The CDK1306 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 CDK1306
low input capacitance of only 5pF.
Power dissipation is extremely low at only 160mW typical at 40 MSPS with
a power supply of +5.0V. The digital outputs are +3V or +5V, and are user
selectable. The CDK1306 is pin-compatible with an entire family of 10-bit,
CMOS converters (CDK1304/05/06), which simplifies upgrades. The CDK1306
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 CDK1306 is available in 28-lead SOIC and 32-lead small (7mm square)
TQFP packages over the commercial temperature range.
