Data Acquisition - Analog to Digital Converters (ADC) are a type of electronic device used to convert an analog signal into a digital signal. The LTC2380CMS-16#PBF, a low power, 16-bit monolithic sigma-delta Analog to Digital Converter (ADC) with internal reference, is one of the most advanced ADCs in the market, providing a high degree of accuracy, high speed and low power operation. In this article, the application field and the working principle of the LTC2380CMS-16#PBF ADC will be discussed.

Application Field

The Differential/Single-Ended input LTC2380CMS-16#PBF gives sixteen bits resolution in a tiny form factor. With a sampling rate of 100Ks/S and low power drain, it is widely used in a variety of applications. When used for automotive and industrial applications, the LTC2380CMS-16#PBF provides an excellent measurement and system resolution. With a wide input range from 0V to VREF, it is suitable for the precise voltage measurements in some of the most advanced motor control applications. In addition, its low power drain and small 7-pin SOT-23 package makes it ideal for portable applications such as consumer and medical products. Furthermore, its excellent signal-to-noise ratio also makes it suitable for audio and telecommunications applications.

Working Principle

The LTC2380CMS-16#PBF is a low power 16-bit monolithic sigma-delta ADC which converts analog signals into digital signals using sigma-delta technology. It works by combining successive approximation architecture with a sigma-delta modulator. The successive approximation architecture samples the analog input voltage at regular intervals and uses a digital to analog converter to generate quantized digital tap levels. The digital tap levels are then compared with a reference voltage, and the output of the comparison is determined by a suitable logic circuit. The output of the logic circuit is then used to select the correct digital tap from the digital to analog converter. Ultimately, the digital output is a very precise reflection of the original analog value.

The sigma-delta architecture works by converting the analog signal into a pulse-width modulated (PWM) signal. The PWM signal is then passed through a digital filter and an analog low-pass filter in order to obtain the final digital output. The output of the digital filter is a very nice representation of the original analog signal.

The LTC2380CMS-16#PBF has an internal reference voltage which can be adjusted to ensure maximum accuracy. It also includes a wide range of options such as input multiplexing, internal or external reference usage and power generation options. The LTC2380CMS-16#PBF also features integrated features such as an on-chip gain settings and an adjustable offset.

Conclusion

The LTC2380CMS-16#PBF, with its low power, 16-bit resolution, wide input range and integration of important analog features, is a suitable Analog to Digital Converter for automotive, industrial, consumer and medical applications. It operates based on successive approximation architecture and sigma-delta modulator, enabling a precise representation of an analog signal into digital form. The LTC2380CMS-16#PBF is an excellent choice for exact voltage measurements and audio and telecommunications applications.
