The DC2222A-B is an analog-to-digital converter (ADC) Evaluation Board specifically designed to evaluate the performance of Texas Instruments\' C2000 Real-Time Control MCU. Unlike most ADCs, the DC2222A-B utilizes a two-step design to weigh the analog input by both digital and analog means, so as to reduce noise and distortion from the in-rush of electrical noise signals.

The DC2222A-B has an analog input range of up to ±5V, making it suitable for many applications where precise measurements of instantaneous voltage changes are required. The solution offers 12-bit resolution and includes a host MCU, which utilizes the C2000 microcontroller\'s C-programmable analog-to-digital converter peripheral, providing an essential tool for developing sophisticated real-time control solutions.

In operation, the DC2222A-B first processes the input signal from the analog source via its external ADC peripheral. The analog signal is then converted to a digital signal, which is then sent to the TI MCU, where it is further processed and converted back into analog form for output. This two-step approach reduces noise and distortion from the in-rush of electrical noise signals, as the signal is sampled and processed multiple times before reaching the MCU.

The DC2222A-B also features a selectable digital filter, which can be used to filter out unwanted noise and distortion by limiting the frequency response of the digital output signal. The filter is adjustable to achieve the desired noise and distortion levels for a given application. This flexibility also allows for the fine-tuning of the noise and distortion level for specific applications.

In addition, the DC2222A-B has a wide range of enabling signals, such as start/stop, reset and interrupt signals, which can be used for advanced signal control and data routing operations. An on-board LED display provides easy access to diagnostic information, such as performance measurements, error codes and calibration information.

The DC2222A-B evaluation board is an easy-to-use, comprehensive solution for the development of analog-to-digital converter applications, providing users with a complete and comprehensive evaluation platform for the C2000 Real-Time Control microcontroller. The board\'s easy-to-use configuration allows users to quickly evaluate the performance of their analog-to-digital converter solutions in a wide range of applications, from robotics and automation to science and engineering.
