The EVAL-AD7656-1CBZ (EVAL-AD7656-1CBZ) evaluation board from Analog Devices is an Analog to Digital Converter (ADC) that features 2-channel, 24-bit, low power, differential input, simultaneous sampling, low-to-medium frequency ADCs. The device is designed to operate from a single 5V to 24V supply, and there is also an evaluation system available for testing purposes.

The EVAL-AD7656-1CBZ has 16-bit Delta-Sigma Analog to Digital Converter (DS ADC) and is capable of sampling up to 200kSPS. Its two-channel simultaneous sampling supports both multi-voltage and low-voltage signal measurements. The device includes a programmable gain amplifier (PGA) and two internal voltage regulators to provide the necessary voltage range and current regulation.

The EVAL-AD7656-1CBZ has a wide range of outputs, from 4 single-ended and 2 differential channels to full-scale differential output with two separate voltage ranges. The maximum resolution of the device is 24 bits with a 75dB SNR. The board also supports a variety of different word lengths, including 8-bit to 24-bit output.

EVAL-AD7656-1CBZ is mainly used in industrial applications that require high precision measurements, such as fluid level measurements and temperature measurements. In these cases, the device provides accurate data acquisition with minimal power consumption. Additionally, its support for low-voltage and multi-voltage signals makes it suitable for a variety of applications.

The main operating principle behind the EVAL-AD7656-1CBZ is its ability to convert an analog signal into digital data, which is then read by the microcontroller on-board. The internal ADCs are driven by an analog-to-digital conversion circuit which converts the input signal into a digital representation. The resulting data is then stored in an internal register, which can then be read and interpreted by the microcontroller.

The device also features two voltage regulators, allowing for programmable adjustment by the user to suit the needs of the application. This allows for accurate and stable readings even when varying supply voltages are experienced. In addition, the on-board PGA enables the user to set a gain of up to x128, which can be used to increase the resolution of the output signal.

The EVAL-AD7656-1CBZ is a great choice for industrial applications where accuracy and low power consumption is essential. Its 16-bit Delta-Sigma ADC and 24-bit resolution ensure accuracy and fast response, while the low-voltage and multiple-voltage capabilities make it suitable for a variety of applications. In addition, the programmable gain amplifier allows for adjustable gain, ensuring that the device can meet the precision needs of any application.
