The EVAL-AD7653CBZ is specifically designed to evaluate the AD7653, which is a 200 Ksps, 4-channel, 12-bit successive approximation register analog to digital converter (ADC). This evaluation board provides the components necessary to evaluate the features of the AD7653. It also has the potential to include additional features needed for specific applications.

The EVAL-AD7653CBZ evaluation board is designed for direct connection to a PC and to provide an instant working platform that users can quickly configure for various applications. It contains sockets to accept signal-level samples from analog source, allowing the user to evaluate a wide range of sample sources. It operates with both 3.3V and 5V power supplies, as well as with low-power sources such as batteries.

The EVAL-AD7653CBZ is targeted primarily at application fields such as data acquisition systems, test instrumentation, industrial process control, and signal monitoring, due to its low power consumption, high sampling rate, and 10- to 12-bit resolution. In particular, it is ideal for low-power systems since it requires only a single 3.3V DC supply and consumes less than 5 mA current.

The working principle of the EVAL-AD7653CBZ is based on successive approximation register (SAR) technology, which is a type of analog to digital converter (ADC). The core logic of this ADC is a SAR circuit, which consists of two major components: the converter itself, and a charging network. The SAR circuit starts with the charge redistribution cycle. In this stage, the analog input voltage is multiplied by a series of fixed reference voltages to produce a set of bits that determine the exact value of the voltage being measured. These bits are then stored in a shift register for processing and data transfer.

Once the data is stored in the shift register, it is read out simultaneously with a clock pulse and then placed on the appropriate output. This data can then be read out into the rest of the system or used for further processing. Finally, the charge-redistribution cycle is repeated to refresh the SAR and ensure accuracy.

The major benefit of SAR technology is its relatively low switching current requirements, allowing designers to reduce power consumption and improve overall system reliability. In addition, SAR ADCs offer high speed conversion and resolution up to 12 bits. Furthermore, SAR ADCs are well-suited for applications that require precise measurements over a wide range of input voltages.

The EVAL-AD7653CBZ evaluation board is designed to simplify the process of evaluating the AD7653. It features dual power supplies and low-power battery operation, as well as plug-in modules for signal-level samples. With its powerful features, the board facilitates the process of designing and testing for 4-channel SAR ADC applications.
