It features low noise, low power consumption and low power supply voltage requirements, while still delivering excellent linearity, high SNR and SFDR performance. The excellent dynamic performance of the ADS62P49IRGCT makes it a suitable choice for a wide range of data acquisition applications.

Working Principle of ADS62P49IRGCT

The ADS62P49IRGCT is a Delta-Sigma (ΔΣ) converter, which is a modern analog-to-digital converter (ADC) technology that uses oversampling and noise shaping to increase the resolution of the conversion process. The ΔΣ converter works by periodically taking samples of the input signal and then converting each sample into a digital bitstream. The bits in the bitstream are then passed through a feedback loop that shapes the noise, which then reduces it to a desirable level. This digital bitstream is then converted into a digital value that is close to the original analog value.

The ΔΣ converter in the ADS62P49IRGCT has an integrated modulator and decimator that can be used with an external Clock Reference. The modulator and decimator are used to periodically sample the input signal and then store it in the register. The modulator processes the digital bitstream generated by the decimator and passes it through a noise shaping filter. The noise shaping filter removes the unwanted noise in the signal and shapes the noise to a desirable level. The resultant digital value is then output from the decimator.

The ADS62P49IRGCT provides excellent dynamic performance and is suitable for a variety of data acquisition applications. It features a wide input range and a selectable output data rate up to 1MSPS. It also includes a multiplexer option that allows for the selection of up to 8 single-ended input signals. The excellent dynamic performance of the ADS62P49IRGCT makes it a suitable choice for a wide range of data acquisition applications.
