The DC851A-X is an evaluation board that serves as an analog to digital converter (ADC). It enables the user to explore the world of analog-to-digital conversion. The board provides a way of quickly evaluating analog-to-digital converters and quickly developing systems which require such converters. The board is produced and sold by the company Analog Devices.

Operation

The DC851A-X operates using an exterior upstream analog signal. This signal is applied to the board at one of the three analog input channels. The board then converts the analog voltage or current signal to a digital signal. The output of the board is a 16-bit serial data stream. This can then be connected to an external microprocessor or other digital device for further data manipulation.

Features

The DC851A-X includes many features to make the analog-to-digital conversion process easier. These features include multiplexed analog inputs, over-temp protection, multiple digit data bus outputs and clock generation. The board also includes a power supply, temperature sensor and signal conditioning modules. The user also has the ability to access and control the board via a UART or USB port.

Application Fields

The DC851A-X is designed to be used in a variety of different applications. These include scientific instrumentation, laboratory testing, data acquisition, factory automation and embedded systems. The board has the ability to convert a wide range of signals from temperature, pressure, voltage and current. This enables it to be used to measure and record data in many different scenarios.

Working Principle

The DC851A-X operates following a specific standard according to the datasheet provided by the company Analog Devices. When an analog signal is applied to one of the analog input channels, the board converts this to a digital signal. This is accomplished by first amplifying and filtering the incoming signal using a low pass filter and then passing it through a digital-to-analog converter. The digital-to-analog converter then converts the analog signal into a 16-bit serial data stream. This data stream is then outputted from the board.

Conclusion

The DC851A-X is an evaluation board that provides a user with an analog-to-digital converter. It has been designed for use in applications such as scientific instrumentation, laboratory testing, data acquisition, factory automation and embedded systems. The board operates using an exterior upstream analog signal. It amplifies and filters the signal and then passes it through a digital-to-analog converter. The output is a 16-bit serial data stream. The DC851A-X provides a simple, cost-effective way to explore the world of analog-to-digital conversion.
