Working Principles

The ADS42LB69IRGCT utilizes a pipeline architecture for high-speed analog-to-digital conversion. It consists of multiple stages, each performing a partial conversion of the input signal. The converted data from each stage is then combined to produce the final digital output.

The analog input signal is first amplified by the programmable gain amplifier (PGA) to match the desired input range. The amplified signal is then sampled at a high rate using a sample-and-hold circuit. The sampled values are subsequently processed through the pipeline stages, where each stage performs a portion of the conversion process.

In each stage, the analog signal is successively approximated by comparing it with a set of reference voltages. The resulting digital codes from each stage are combined to form the final digital output, which represents an accurate digital representation of the original analog input signal.
