System-Level Approach Enables the Design of Precision, High Density, Isolated Analog Output Module for Process Control

July 28, 2020 by Analog Devices, Inc.

Design Note Overview

When designing channel-to-channel isolated analog output modules for process control applications, such as programmable logic controller (PLC) or distributed control system (DCS) modules, the main trade-off is usually between power dissipation and channel density. As module sizes shrink and channel densities increase, the power dissipation per channel must decrease to accommodate the max power dissipation budget for the module. Higher channel density also means that there is less PCB real estate available for each channel.

In this design note from Analog Devices, learn more about the AD5758 and ADP1031 system-level approach and how it can help achieve power dissipation of less than 2 W for all eight channels operating under worst-case power dissipation conditions.
