Data acquisition systems are evermore present in our society. These tasks require data converters, such as ADCs and DACs, which are specialized microchips able to encode and decode analog signals into digital equivalents. The AMC1305L25DWR is a special purpose low-power ADC and DAC with advanced features, making it ideal for data acquisition and industrial applications.

Application Field

The AMC1305L25DWR is a data acquisition device specifically designed for applications that require high resolution as well as high coordination accuracy. As such, it is particularly well-suited for process control, metrology and medical equipment such as laboratory centrifuges, digital pressure gauges, or radiology and MRI machinery, where miniaturization, speed, accuracy and noise rejection are of high importance.

The device can also be used in industrial applications requiring direct sampling of analog and digital inputs, like automotive control systems or industrial motor control. It features up to 16 active points per axis with full range of motion monitoring, as well as programmable pulse width measurement and generation with 4 outputs.

Working Principle

The AMC1305L25DWR is a low-power ADC and DAC with versatile features. Its onboard programmable signal conditioning provides levels shifting, dynamic range adjustment and optional signal filtering, while its 6-channel differential input architecture gives it impressive noise immunity and measurement accuracy.

The ADC and DAC are based around a two-stage pipelined architecture, with each analog input channel being sampled twice by different phases. This is followed by a digital intermediate sampling phase, which converts the analog signal into digital form before feeding it to the successive pipeline stages for further digital processing.

The device also features an on-chip high-speed digital signal processor (DSP) which is used for low-noise filtering, signal averaging and signal flattening, as well as gains and digital offset adjustment, eliminating the need for manual calibration.

Conclusion

In conclusion, the AMC1305L25DWR is a low-power ADC and DAC with advanced features and capabilities, making it ideal for data acquisition and industrial applications which require high resolution as well as high coordination accuracy. The device features an onboard programmable signal conditioning with levels shifting, dynamic range adjustment and optional signal filtering as well as a 6-channel differential input architecture with impressive noise immunity and measurement accuracy.
