Software-configurable AFE integrates ADC for process control
Designers can create input modules for multiple product iterations using the AD4110-1 analogue front end (AFE) with integrated 24-bit ADC for industrial process control systems.
The AD4110-1 is a universal input AFE from Analog Devices. It has a differential programmable gain amplifier (PGA) that offers 16 gain settings from 0.2 to 24 and provides internal, front-end diagnostic functions to indicate over-voltage, under-voltage, open wire, over-current, and over-temperature conditions.
The high voltage input is thermally protected, over-current limited, and over-voltage protected.
The integrated ADC allows customers to design an input module that they can configure for multiple functions, which saves “significant” R&D cost, says Analog Devices, as well as reducing time to market and requiring less design resources.
The high voltage inputs of the AD4110-1 are software configurable for current or voltage signals, allowing direct interface to all standard industrial analogue signal sources. One reference design replaces many, reducing module size and decreasing cost of ownership. Software-configurable I/O is a key factor in the implementation of industry 4.0.
The AD4110-1 is available now in 40-lead LFCSP packages.
