The PCM1750U/1K is an advanced analog-to-digital converter (ADC) specially designed to provide high speed, low power consumption, excellent linearity, and wide bandwidth to the measuring and monitoring of still or moving force, pressure and acoustic signals. It is engineered with state-of-the-art analog-to-digital signal processing technology and provides large signal dynamic range, and high precision and accuracy. This ultra-fast ADC with its low power and energy efficient design is ideally suited for applications such as medical imaging, ultrasound, vibration monitoring, quality control and machine-to-machine communication.

PCM1750U/1K Application Field and Working Principle

The PCM1750U/1K can be used for a variety of applications that require high-speed, low-power, and high-precision data acquisition. It is specially designed for low-level signals, including force transducers, pressure sensors, and acoustic transducers.The PCM1750U/1K utilizes a multi-channel architecture that includes two groups of 8-bit ADC plus one group of 24-bit ADCs, providing higher accuracy and extended dynamic range. It supports up to 10 input channels and provides simultaneous conversion of multiple channels. It has an adjustable sampling rate of up to 600 MHz and can measure frequencies up to 51 MHz. The chip is also equipped with built-in signal processing functions and supports active noise canceling and dynamic range boosting to obtain higher accuracy measurement results.

The PCM1750U/1K also includes two modes of operation, a Fast Mode and a High Resolution Mode, which can be switched between with a simple command to enable the user to modify the resolution and sampling rate for the best possible result. In Fast Mode, fewer bits are used to achieve higher sampling rates. The High Resolution Mode uses more bits to achieve a greater dynamic range. Both modes offer 8-bit linearity.

The PCM1750U/1K employs delta-sigma modulation, a technique used to improve the precision and accuracy of analog-to-digital conversions. This technique relies on a combination of analog and digital signals to achieve higher resolution and lower noise levels.The PCM1750U/1K also features advanced power saving features. It features Auto On Mode which reduces power consumption when no signals are present and switches off when no more data is received. This helps reduce power consumption and prolong battery life. It also features a Sleep Mode which reduces the power consumption to only 1.2 µA during an idle state, and has a low-power deep sleep mode which can be used for applications that require low levels of power.

The PCM1750U/1K is an ideal choice for a wide range of data acquisition applications. It offers high speed, low power consumption, excellent linearity, and wide bandwidth to ensure accurate measurements and monitoring in various demanding applications. With its advanced signal processing technology, it is able to provide high accuracy and precision measurements even in challenging conditions.
