The AD260 is designed using Analog Devices new IsoLogic circuit architecture to isolate five digital control signals to/from a microcontroller and its related field I/O components. Six models allow all I/O combinations from five input lines to five output lines, including combinations in between. Every AD260 effectively replaces up to five opto-isolators while also providing the 1.5 W transformer for a 3.5 kV isolated dc-dc power supply circuit.

The REF02 precision voltage reference providesa stable 5V output that can be adjustedover a ±6% range with minimal effect on temperature stability. Single-supply operation over an input voltage range of 7 V to40 V, low current drain of1 mA, and excellent temperature stability are achieved with an improvedband gap design. Lowcost, low noise,and low power make the REF02 an excellent choice when ever a stable voltage referenceisre quired. Applications include DACs and ADCs, portable instrumentation, and digital volt meters. The versatility of the REF02 is enhanced by its use as a monolithic temperature transducer. For new designs, refer to the ADR02.
