General Description
The CDK1304 is a 10-bit, low power analog-to-digital converter capable
of minimum word rates of 25 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 CDK1304
low input capacitance of only 5pF.
Power dissipation is extremely low at only 135mW typical at 25 MSPS with
a power supply of +5.0V. The digital outputs are +3V or +5V, and are user
selectable. The CDK1304 is pin-compatible with an entire family of 10-bit,
CMOS converters (CDK1304/05/06), which simplifies upgrades. The CDK1304
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 CDK1304 is available in 28-lead SOIC and 32-lead small (7mm square)
TQFP packages over the commercial temperature range.
