This document introduces a high performance, single-ended, precise DC DAC configuration using AD5426/AD5432/AD5443 series precision multiplier DACs, low noise operational amplifier AD8065 and precision reference voltage source ADR01.
The note provides a detailed circuit design that employs AD5426/AD5432/AD5443 series 8‑12‑bit multiplication DACs together with the low‑noise AD8065 operational amplifier and the ADR01 precision reference. It includes design considerations, performance advantages, and component selection guidance for high‑performance, single‑supply DAC applications.
The document also contains legal disclaimer text, revision history, and references to related Analog Devices design tools and datasheets. It mentions alternative reference parts (ADR02, ADR03, ADR441, ADR445) and provides typical specifications such as offset voltage and bias current for the AD8065. This manual is written in Chinese.
