Product Summary

The AD574AKD is a complete 12-bit successive-approximation analog-to-digital converter with 3-state output buffer circuitry for direct interface to an 8- or 16-bit microprocessor bus. A high precision voltage reference and clock are included on-chip, and the AD574AKD guarantees full-rated performance without external circuitry or clock signals.
