ADS5422EVM

The ADS5422EVM is an evaluation module for the dual-channel 12-bit low power ADC. This module is designed to help customers develop and evaluate the ADS5422 ADC, an industry-leading analog-to-digital converter. The on-board 16-pin ADC connector allows direct connection to a microcontroller or other device for testing and application development. Its features, such as the two unipolar and two bipolar input ranges, and the programmable gain amplifier, make this EVM well suited for use in many different applications.

The ADS5422EVM is designed to provide for the testing of the ADS5422 low power ADC. The ADS5422 is a dual channel, 12-bit, low power ADC that includes an offset calibration for precise measurements. This module offers two unipolar and two bipolar input ranges, programmable gain amplifier, high sample rate, low off-set voltage, and low power consumption.

The working principle of the ADS5422EVM is based on the ADC\'s analog-to-digital converter. It uses the successive approximation register (SAR) for its AD conversion. The module starts with the most significant bit (MSB) of the digitized signal in the SAR and passes it by the comparator. The comparison between the digital signal in the SAR and the analog input then determines the state of the MSB, which is either “1” or “0”. This process is repeated for each of the other bits until all 12 bits are read, yielding the digital representation of the analog input signal. The ADS5422EVM standard cycle time is 16 samples per second.

The ADS5422EVM can be used in a variety of applications as the 12-bit resolution of the converter enables the module to accurately capture analog signals from a range of powers and frequencies. Its low power consumption allows this module to be used for mobile solutions, as well as for industrial systems. Furthermore, its various voltage ranges make the module extremely versatile and allows its use in a variety of applications. Some of the most popular applications of the ADS5422EVM are:

• Industrial monitoring systems
• Portable medical equipment
