The CDB 5560-2 is an evaluation board integrating an analog-to-digital converter (ADC). Developed by Texas Instruments (TI), the board features an analog input range of 0-5V, a 24-bit variable gain amplifier, a 2.5V low-noise voltage reference, an optical-isolator for digital interface, and a digital offset and gain trim function. By taking advantage of the optional micro-controller included with the evaluation board, users are able to control and adjust settings from a computer, such as gain, offset, sampling rate, channel selection, and timing parameters.

This evaluation board is particularly useful for a wide variety of applications, notably audio signal processing, image and video transformation, precision instrumentation, medical imaging, and communication. Its 24-bit A/D resolution can provide a dynamic range of 144 dB, with sampling rates up to 40 kHz, available through the use of the optional micro-controller. Additionally, the board also features a low-noise voltage reference for high-precision measurements, with an input impedance of 10 MΩ, and a programmable gain amplifier of up to 64 dB.

The CDB 5560-2 is ideal for applications in medical imaging, sonar systems, and robotic navigation systems. Its low-noise voltage reference and 24-bit A/D resolution provide a wide dynamic range of 144 dB and high accuracy performance. This evaluation board also features an analog input range of 0-5V, a digital offset and gain trim function, and an optical-isolator for digital interface. By taking advantage of the optional micro-controller, users are able to control and adjust settings from a computer, enabling precision applications.

The working principle of the CDB 5560-2 is fairly straightforward. When an electrical signal is applied to its analog input, it is converted into a digital value proportional to the magnitude of the input signal. The analog input signal is amplified by the programmable gain amplifier, and then fed into the analog-to-digital converter. The A/D then converts the analog signal to a digital word, comprising of 24 bits, representing the input amplitude. This digital value is then outputted to an interface, such as the optional microcontroller, enabling the user to adjust and control settings.

In conclusion, the CDB 5560-2 evaluation board is an ideal solution for a wide variety of applications. By taking advantage of its high-performance 24-bit A/D resolution, low-noise voltage reference, digital offset and gain trim function, as well as its highly integrated design, users are able to develop applications in precision instrumentation, medical imaging, and communication. Additionally, the board features various adjustable settings, such as gain, offset, sampling rate, and timing parameters, enabling even more precise control with the optional microcontroller.
