Working Principle

The LTC2471CMS#PBF uses a delta-sigma modulator architecture to convert analog input signals into digital outputs. Delta-sigma modulation is a low-power analog-to-digital conversion technique that uses capacitors to sample and integrate the input voltage. The integrated voltage is then compared to a reference voltage, which is provided by an on-chip precision voltage reference. Based on the comparison, the output is either a one-bit change or a zero-bit change.

The output is then fed into an on-chip digital filter, which evaluates the one-bit output from the comparator and determines the final digital output of the ADC. The filter is designed to reject noise on the input and to limit the effects of quantization errors, resulting in improved accuracy and resolution. The LTC2471CMS#PBF has an effective data rate of 200ksps, which ensures fast and accurate A/D conversion.

The LTC2471CMS#PBF is designed to be easy to use and configure. The device supports a wide range of input voltages and is flexible enough to be used in a variety of applications. The device can be configured to output a standard voltage such as 4-20mA, 0-10V, or 0-5V, or it can be configured to output a pulse-width modulated signal that can be used to control a motor or other equipment. The onboard voltage reference ensures that the output remains accurate and stable over temperature and supply voltage changes.

Conclusion

The LTC2471CMS#PBF is a high-resolution, low-power, 24-bit Delta-Sigma analog-to-digital converter (ADC).
