Data Acquisition - ADCs/DACs - Special Purpose: CS5364-DQZ Application Field and Working Principle

Data acquisition (DA) systems are used to capture digital information from physical devices for a variety of purposes. This can range from simple data logging of a variable temperature to monitoring and control of process parameters in an industrial environment. ADCs/DACs are specialized integrated circuits that are used to convert between different types of electrical signals, such as from analog to digital and vice versa. The CS5364-DQZ is a 3-channel, 24-bit, D/A converter (DAC) with an integrated filter and reference voltage generator. This device integrates three high performance filters, multiple reference voltages, ultralow drift and low power consumption into a single IC, making it ideal for precision data acquisition systems.

The CS5364-DQZ is widely used in a variety of high performance, low power applications including military/aerospace, industrial and medical. It can be used to convert digital signals into analog signals such as audio, video or control signals. The device is also ideal for applications where low power consumption and high accuracy are essential, such as in test and measurement equipment or power electronics.

The working principle of the CS5364-DQZ is based on the conversion of digital signals into analog signals using a combination of digital coding and analog filtering. A parallel combination of analog bandpass filters is used to separate the digital components of the signal from the analog components. The digital components are then converted to analog by digital-to-analog converters (DACs). The output of the digital-to-analog conversion is then filtered using the on-chip analog filter.

The digital input data is encoded in three separate data formats: I2S, LPCM and DQZ. The I2S and LPCM formats use left-justified or right-justified data word lengths of 8, 16, 24, 32 and 64 bits. The DQZ format is a 24-bit delta-sigma format optimized for low power. The ability to use multiple data formats makes the CS5364-DQZ suitable for a variety of applications.

The power consumption of the CS5364-DQZ is extremely low, with a typical operating current of just 300 microamps. The high precision of the device also makes it suitable for applications where overall accuracy and linearity are critical. In addition, the device includes a built-in reference voltage generator which simplifies the design of a power supply.

The CS5364-DQZ is a high performance, low power solution for transmitting digital data into analog signals. Its integrated filters, multiple reference voltages, ultralow drift and low power consumption provide an ideal solution for precision data acquisition systems.
