It is produced by Silicon Labs and is part of the company\'s SDC1740 family of special purpose signal data converters, which utilize Silicon Labs\' patented architectures and low power speed enhancements for better signal-to-noise ratios, longer device life, and enhanced system performance.

Application Field

The SDC1740-411B is designed primarily to meet the needs of medical applications such as electrocardiography equipment and home monitoring medical instrumentation. Its other application field includes test and measurement equipment, automotive instrumentation, consumer electronics, communications, industrial machines, and sensor systems. The SDC1740-411B has built-in capabilities for acquiring high-resolution analog signals, digital signals, and mixed-mode signals for converting data from one type of signal to another. Additionally, it offers very low harmonic distortion and low power consumption, and is also available in a 32-bit wide version for more efficient data acquisition.

Working Principle

The SDC1740-411B is an advanced signal-data converter that offers excellent performance in response to a wide variety of data conversion tasks. It utilizes the company\'s patented process-oriented architecture and the patented Multi-Tap Delay Line (MTDL) technology to achieve high resolution, long-term stability, and fast sampling rates. MTDL technology is based on the time-dependent linearity concept, which reduces distortion in response to high frequency signals.

At the heart of the SDC1740-411B is the converter\'s patented Multi-Tap Delay Line (MTDL) technology, which enables it to achieve high resolution, long-term stability, and fast sampling rates. This is achieved by using the dynamic linearity concept and placing taps at intervals about the center point of the signal, thus providing greater resolution with less harmonic distortion. The SDC1740-411B is capable of sampling 16-bit resolution, 12-bit dynamic linearity, and can reach a sampling rate of up to 250kHz.

The SDC1740-411B utilizes its Integrated ADC and DACs for digital-to-analog conversion, as well as integrated Flexible DC and Clever Mixed-Mode Digital Inputs for data acquisition. The DC inputs are enabled to provide low noise, tight performance, and long-term accuracy. The Clever Inputs enable inputs with both digital and analog signals to be acquired by the same channel while having no effect on the response time or noise performance.

The SDC1740-411B is designed to operate in a wide range of temperature and humidity conditions, and can do so at industrial and automotive rated temperatures. The device is EMC certified, which means it has passed standard testing to ensure proper operation in varying levels of electrical noise. Additionally, the device is able to operate in a wide range of voltage supplies, being either a single voltage supply or a dual voltage supply.

Conclusion

The SDC1740-411B is a versatile signal data converter for use in a variety of applications, such as medical instrumentation, automotive instrumentation, consumer electronics, communication, and industrial machines. It utilizes Silicon Labs\' patented architectures and low power speed enhancements for better signal-to-noise ratios, longer device life, and enhanced system performance. The device is highly reliable and can operate in a wide range of temperature and humidity conditions, and voltage supplies.
