The DC847A is a highly versatile and powerful evaluation board from Texas Instruments designed to support Analog to Digital Converters (ADCs). It is a flexible system that includes extensive signal conditioning, powering and data capture features. The DC847A board is ideally suited for evaluating the performance of a wide range of ADCs, including those from Texas Instruments such as the ADS7500, ADS7000, ADS6300 and ADS541. The board can also be used for testing other types of converters, such as Digital to Analog Converters (DACs) and any other digital signal processor (DSP).

The DC847A evaluation board is designed to allow a range of user-configurable features and signals, enabling the board to accommodate a variety of different channels. Each board channel is independently configurable and includes adjustable gain and offset, two separate programmable power supplies and adjustable output bias. The board also contains a variety of on-board sensors for data acquisition. To accommodate high-speed sampling and analog signal processing, the board supports both analog and digital signal conditioning features, such as precision analog gain and offset trim, adjustable timing control, delta-sigma filters, decimation and optional signal conditioning functions.

The DC847A also offers a range of data capture features, such as data storage, memory transceivers and data analysis software. The board can communicate data to a PC through the USB 2.0 interface, allowing for real-time analysis of captured data. The board is also compatible with the Texas Instruments control software, enabling users to manage board configuration directly from their PC.

At the core of the system is the 24 bit DC847A ADC core, which provides a high resolution, low noise signal conversion of up to 24 bits. The core is powered by a 5V supply and features four different selectable ranges. The ADC core has been designed with a thermal shutoff mechanism to ensure safe operation in high temperature conditions. The onboard level shifter also provides the capability to interface with both low and high-level sources.

The DC847A is also suitable for a range of different signal conditioning applications and instrumentation, such as low frequency signal filtering, synchronous sampling, high speed data acquisition and frequency modulation. It is a highly precise device and works perfectly in conjunction with other instruments such as oscilloscopes. The onboard on-screen graphical user interface (GUI) provides an intuitive and inclusive platform for easy configuration and operation of the device.

In summary, the DC847A evaluation board from Texas Instruments is a powerful and versatile Analog to Digital Converter specifically designed for evaluating the performance of a wide range of ADCs. The board supports adjustable gain and offset, two separate programmable power supplies and adjustable output bias, as well as various data acquisition sensors and signal conditioning features such as delta-sigma filters, decimation, and optional signal conditioning. Additionally, the board is able to communicate data to a PC through the USB 2.0 interface and is also compatible with the Texas Instruments control software. The DC847A is a highly precise device and is ideal for signalling conditioning and instrumentation applications.
