Designed for a variety of applications, it is ideal for a range of data acquisition systems used in medical, automotive, industrial and consumer applications. This article will discuss the various application fields and working principles of the CS5371A-ISZ.

Application Field

The CS5371A-ISZ is applicable to a wide range of applications including medical devices, automotive systems, industrial systems and consumer electronics. Medical applications include electrocardiography (ECG), digital X-ray, tomography imaging systems, non-invasive body sensors, and glucose and other vital-sign monitoring systems. In automotive applications, the CS5371A-ISZ is used in inertial navigation systems, engine control systems, body electronics and sensors. Industrial applications include industrial process control and test benches. For consumer electronics, the CS5371A-ISZ supports digital media players, GPS, digital picture frames and high definition TVs.

Working Principle

The CS5371A-ISZ uses a successive approximation register (SAR) architecture with an internal reference. The ADC comprises of two main parts: the analog input stage and the digital output stage. The analog input stage includes a reference buffer, a comparator, and an analog multiplexer (MUX). The analog MUX allows the user to select between either single-ended or differential analog inputs. The reference buffer can be set externally or internally, allowing a wide range of input levels to be set by the user. The comparator compares the input voltage against the reference voltage, and produces a digital output that is fed to the digital output stage. The digital output stage consists of a decoder and a 10-bit digital-toanalog converter (DAC). The DAC is used to generate the analog voltage that is output by the device.

In operation, the analog MUX is used to select either a single-ended or differential input. The ADC sample rate is set by the internal oscillator, with a range from 500 kHz to 10 MHz. The reference buffer is used to adjust the internal reference voltage, which is used to compare the input voltage. The output voltage is then generated by the DAC and the result is clocked out via the serial interface. The CS5371A-ISZ offers a fast conversion rate, a low power consumption and a wide range of input voltage ranges, making it ideal for many different types of data acquisition systems.

Conclusion

The CS5371A-ISZ is a low power, high speed, 10-bit, voltage output Analog-to-Digital Converter (ADC) suitable for a wide range of data acquisition applications. Its successive approximation architecture with an internal reference allows it to handle single-ended or differentially driven signals, with a wide range of settings for the reference buffer to allow for the most accurate conversion possible. Its fast conversion rate, low power consumption, and wide input range make it an ideal device for many different types of industrial, automotive, medical and consumer applications.
