Working Principle of the ADS1241E/1K ADC

The working principle of the ADS1241E/1K ADC is based on the sigma-delta conversion technique which is based on the theory of feedback loop. This technique works by repeatedly sampling the input signal and comparing it to the reference voltage, generating an error signal which is then used to adjust the output. The output is then referred to as the delta-sigma modulated signal which is then filtered and converted to a digital output.

The sigma-delta conversion technique works in two phases. The first phase is the sampling phase where the input signal is sampled and the output is stored in a capacitor. The second phase is the feedback phase where the error signal generated by the comparison is used to adjust the output voltage, resulting in a delta-sigma modulated signal. This signal is then filtered and converted to a digital output.

Conclusion

The ADS1241E/1K is an ADC which is suitable for applications that require high frequency sampling, as well as low power applications. It is based on the sigma-delta conversion technique and is capable of operation over a wide temperature range.
