Working Principles

The ADS1204IRHBTG4 utilizes a sigma-delta modulation technique to convert analog signals into digital data. It employs oversampling and noise shaping to achieve high resolution and accuracy. The input signal is sampled at a high rate and the resulting data is processed through a digital filter to remove noise and improve the signal-to-noise ratio. The converted digital data can then be further processed or transmitted for analysis.

Detailed Application Field Plans

The ADS1204IRHBTG4 is well-suited for a wide range of precision measurement applications, including but not limited to: - Industrial process control - Medical instrumentation - Data acquisition systems - Test and measurement equipment - Audio signal processing
