The CS5346-DQZ is an advanced, high performance resolving, 16-bit digital-to-analog converter (DAC) designed primarily for audio applications. The advanced delta-sigma architecture combines a 4-bit resolution, 4-stage quarter-wave delay line and a 2-stage low-pass filter with an advanced delta-sigma modulator that provides a low-noise, linear output. Low power and small size are also key features of the CS5346-DQZ. The CS5346-DQZ is typically used for interfacing digital system to analog output stages in audio systems.

The CS5346-DQZ is designed to work with data transmitted using or modified using the Direct Digital Synthesis (DDS) or the Direct Quadrature Encoding (DQE) format. Data is read into the input shift register and stored in the 2,048-bit delay line, at which point it is clocked into the modulator. The clock rate used with the device is typically 28.8 kHz. The modulator consists of multiple stages of delta-sigma converters, each one receiving and summing the output bits from the previous stages. The output bits from the last stage of the modulator are collected in the output register, and are then available for further processing as needed.

The CS5346-DQZ also includes features to improve performance, such as differential current output, which allows for linearization of the DAC response. The device also includes an Internal Power Supply Rejection Ratio (IPSRR) feature, which allows it to reject input noise from the power supply. The device is designed to meet the accuracy requirements of 16-bit audio systems, and can provide better performance than DACs with lower bit resolution. In addition, the CS5346-DQZ has been designed to provide low power consumption, making it ideal for use in battery-powered applications.

The CS5346-DQZ is capable of providing an analog signal with a dynamic range of greater than 90 dB, which makes it suitable for use in high resolution audio applications. It is also capable of providing an output signal with high fidelity, making it suitable for use in systems requiring high quality audio reproduction. The device has been designed for use in a wide range of audio applications, from consumer audio systems to professional audio systems.

In summary, the CS5346-DQZ is a high performance delta-sigma DAC designed for use in high resolution audio applications. It features high dynamic range, low power consumption, small size, linearization of the DAC response and low noise. The device is suitable for a variety of audio systems, from consumer audio to professional audio. The CS5346-DQZ is an ideal solution for interfacing digital systems to analog output stages.
