AMC1303M0510DWV Integrated Circuits (ICs)

This paper provides an overview of the application field and working principle of the AMC1303M0510DWV, which is classified into the data acquisition - ADCs/DACs - special purpose category.

Application Field

The AMC1303M0510DWV is an ultra-low power differential-input Delta Sigma ADC, designed for low frequency, low-resolution, low-noise data acquisition applications. It features low-power consumption, small size and good performance, making it ideal for portable and battery powered systems. The product also offers a wide input range and low total harmonic distortion (THD), making it suitable for automotive, industrial, consumer, and medical applications, such as factory automation, environmental & energy monitoring, healthcare and wearables.

Working Principle

The AMC1303M0510DWV is a differential-input, low-power Delta Sigma ADC with a 10-bit resolution. In operation, the device converts differential voltage inputs into a single-ended code (1-bit time base) which is then sampled by a low-power digital filter. The filter weights the codes as per its design to produce a 10-bit digital output. The ADC features a dynamic range of +/- 2.5V and an input impedance of >3GΩ, which allows transients to pass without causing errors. The low power consumption of 6 µA/channel makes it ideal for battery powered systems.

The AMC1303M0510DWV also offers excellent noise performance with a maximum total harmonic distortion of -70dBc and a signal-to-noise ratio (SNR) of >73dB for a 0.1kHz input signal. The device also features a built-in programmable over-range protection and clock synchronization feature, which helps to reduce power dissipation during idle periods and extend battery life.

Conclusion

The AMC1303M0510DWV is an ultra-low power differential-input Delta Sigma ADC designed for low frequency, low resolution, low-noise data acquisition applications. It features a wide dynamic range, low power consumption, small size, excellent noise performance and over-range protection. These features make it ideal for portable and battery powered systems, as well as automotive, industrial, consumer and medical applications.
