The PCM1755DBQR is a special-purpose, high-speed data acquisition, analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC) module. This module was specifically designed for applications that require a wide dynamic range, low harmonic distortion and low-noise performance. It is capable of handling high-speed data rates and offers a wide range of features, such as multiple-input clock dividers, a built-in variable gain amplifier (VGA) and a programmable noise-shaping filter.The PCM1755DBQR is based on a 12-bit, voltage-output digital-to-analog converter (DAC) and a differential-input, 8-bit analog-to-digital converter (ADC). The DAC offers high-bandwidth (up to 32Msps) and low-distortion output signals. It features a wide range of programmable parameters, such as gain, time constant, slew rate and output impedance. The ADC features differential-input, 8-bit resolution with a system-level noise floor of -90dBV. The module includes multiple-channel synchronized operation and is capable of handling input data rates up to 400Msps.The PCM1755DBQR is ideal for applications such as handheld and body-worn communications systems, medical instrumentation, communication infrastructure, defense communications, data acquisition and test equipment. It can be used in a wide range of systems, including broadcast, automotive, robotics and industrial automation.The working principle of the PCM1755DBQR is based on the conversion of analog signals into digital signals. The module is able to convert analog signals into digital representations using its ADC. The input signals are sampled at a specified rate, and the digital signals are processed to enhance the accuracy of the data. The DAC then takes the digital signals and converts them back into analog signals for output. The module also includes several digital signal processing algorithms for further enhancement of the data, such as noise-shaping converters and variable gain amplifiers.The PCM1755DBQR module is an excellent choice for high-precision data acquisition, with high-accuracy analog-to-digital and digital-to-analog conversion capabilities. Its low harmonic distortion and low-noise performance make it suitable for a wide range of applications, from communications to test equipment. It can be used in both single- and multi-channel modes, allowing for synchronous operation of multiple channels with a single master clock. The module also offers a range of advanced features, such as adjustable gain, time constants, relative gains and output impedances, to provide users with greater control over the performance of their systems.
