Reference design reduces component count
13 May 2014
The Alameda from Maxim Integrates measures four analogue outputs and is suitable for industrial automation applications.
The company claims that the four-channel analogue output has 33% fewer components than competitive designs.
Industrial programmable logic controllers (PLCs) need multiple, flexible, high accuracy analogue outputs. The sub-system combines four high-accuracy (less than ±0.1%) outputs with a high-efficiency, low-noise power supply controller on a single board. Outputs are configurable to ±10V, ±20mA, 0 to 10V, or 4 to 20mA for current and voltage applications. Other features are automatic error reporting for detecting open and short circuits, brown-outs, and over-temperature conditions.
Schematics, layout files, and firmware are available for immediate use and customisation.
