Data acquisition is an integral part of electronic engineering, and crucial in amplifying, conditioning, and encoding analog signals in a way that can be digitalized, stored, and analyzed. Analog to Digital Converters (ADCs) perform this task, and the LTC1403CMSE#TRPBF series is one of the most reliable and efficient options currently on the market. This series of ADCs provides accuracy, resolution, and speed for a number of different applications and industries.

Overview

The LTC1403CMSE#TRPBF series of ADCs are a part of the larger LTC1403 family. This family includes 12- and 10-bit ADCs (the latter for low-cost applications) with single, differential, and bipolar inputs, along with fast sampling speeds with 76 dB signal-to-noise ratio and 50 dB THD+N (total harmonic distortion plus noise) performance. The LTC1403CMSE#TRPBF series is a 12-bit, self-calibrating ADC designed to work with low-power digital signal processing systems, microcontrollers, and microprocessors. It contains several features that make it suitable for demanding industrial and commercial applications, such as low-power operation, high accuracy, and a guaranteed 0.1% accuracy over temperature. This series of ADCs uses a multiplexed output architecture, which makes it more cost-effective and space-efficient than other ADCs.

Applications

The LTC1403CMSE#TRPBF series is ideal for a wide range of applications in commercial, industrial, aerospace, and medical industries. In terms of commercial use, this series of ADCs are used to bring control and data acquisition to many different types of instruments, such as motor control systems, analyzers, and test benches. On the industrial side, it is suitable for use in industrial distributed control systems and data acquisition. In aerospace, it is used extensively for military and commercial aircraft, as well as flight simulators. Finally, its high accuracy and reliability make it suitable for medical applications such as imaging and patient monitoring.

Principle of Operation

The LTC1403CMSE#TRPBF series utilizes a split architecture which combines the power of digital and analog circuitry for optimized performance. This split architecture splits the components into the analog section, where the input signal is converted to a digital signal, and the digital section, where the configuration and data output is handled. The frequency range of the LTC1403CMSE#TRPBF is from 1 kHz to 8.5 MHz, with excellent linearity, making it suitable for a variety of signals.

The analog section consists of two components, the analog front end and the analog-to-digital converter. The analog front end is responsible for amplifying and conditioning the input signal. It uses the high-stability gain elements to reduce gain drift, which results in higher accuracy. The analog-to-digital converter then converts the analog signal into a digital signal. This converter utilizes a 12-bit flash architecture and auto-calibration to ensure the highest accuracy over temperature.

The digital section consists of the configuration and data output logic. It contains the on-chip logic necessary for configuring the LTC1403CMSE#TRPBF for specific applications, such as setting the sampling rate, threshold level, and gain. It also contains the necessary logic for generating the digital data output.

Conclusion

The LTC1403CMSE#TRPBF series of ADCs from Linear Technologies is a powerful and efficient solution for data acquisition and conversion. It combines the best of digital and analog components for superior accuracy and resolution. Its multiplexed output architecture makes it space and cost-efficient, and its self-calibrating design and wide operating temperature range makes it ideal for a wide range of industrial, commercial, aerospace, and medical applications. The LTC1403CMSE#TRPBF series is an excellent choice for data acquisition and conversion needs.
