In the field of data acquisition, specialized hardware such as analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) are used to convert physical signals into digital format, and vice versa. A particularly useful type of ADC/DAC is the CS35L35-CWZR, which is designed to bring the benefits of both onboard storage and the ability to easily gather data from multiple channels. This article will discuss the working principle and application fields of the CS35L35-CWZR.

The CS35L35-CWZR ADC/DAC is an embedded device featuring a 32-bit Delta-Sigma modulator (DSM) with multiple analog inputs. It features a 14-bit and an 18-bit Analog-to-Digital converter (ADC). The 14-bit ADC is used for basic data acquisition and the 18-bit ADC is used for accurate measurements. It also includes a Digital-to-Analog converter (DAC) that can generate signals up to 1kHz. The device also supports various I/O interfaces such as SPI, I2C, UART and USB.

The CS35L35-CWZR ADC/DAC is designed to be used in real-time systems. It supports both burst and single-channel operation, enabling simultaneous sampling of multiple channels, and has an onboard flash memory that allows for data storage up to 128ksamples. This makes it suitable for applications such as vibration and acoustic analysis, where high accuracy and resolution is required. Additionally, the device can be used to monitor various environmental conditions, such as temperature and humidity.

The working principle of the CS35L35-CWZR ADC/DAC is based on the Delta-Sigma modulation technique. This technique combines a number of 1-bit DACs, known as modulators, to achieve higher resolution and accuracy than with single-bit converters. The modulators are connected to the analog signals via a network of sampled-data filter(s). The filtered signals are sent to a 1-bit comparator or D-A converter, which converts the input signals into 1-bit digital signals.

The output of the comparator is then sent to a digital filter, called the decimation filter, which reduces the sampling rate, removes unwanted signals and reduces the overall noise level. This filtered signal is then converted to a digital output by a 16/32-bit data converter. The device also supports a range of programmable input gain setting and adjustable offset values, allowing for custom configuration of the device.

The CS35L35-CWZR ADC/DAC offers several advantages over traditional converters, such as a higher resolution and accuracy and reducing the need for external components. Furthermore, it supports a range of communication protocols, making it suitable for distributed networks. Its features also make it suitable for use in a range of medical applications, such as portable medical instruments, as well as engineering and industrial applications, such as process control, test and measurement, and audio-visual systems.

To summarize, the CS35L35-CWZR ADC/DAC is an embedded device featuring a Delta-Sigma modulator for analog-to-digital and digital-to-analog conversion. It is mainly used in real-time systems, such as medical and industrial applications, that require high accuracy and resolution. The device offers several advantages including reduced power consumption, higher resolution and accuracy, and support for multiple communication protocols. With its ability to store data onboard, the CS35L35-CWZR is a versatile device that can offer a range of advantages in various applications.
