Working Principle of ADS1148IRHBR

The ADS1148IRHBR utilizes a delta-sigma architecture for analog to digital conversion which means that the analog signal is sampled and converted into a digital signal in multiple steps. The first step is to sample the analog signal to obtain an approximate Digital signal. The second step is to high-level, low-noise signal conditioning in order to reduce any kind of noise and jitter. The third step is to use the sigma-delta modulation in order to convert the analog signal into a digital signal. Finally, the digital signal is decoded and the digital value is available.

The sigma-delta architecture of the ADS1148IRHBR makes it a high-precision and low-noise ADC. The gain error and offset error are very small making it especially suitable for applications where high-precision and accuracy are required. It also has low current consumption which makes it ideal for applications that require low-power operation.

In conclusion, the ADS1148IRHBR is a 8-channel, 24 bit sigma-delta analog to digital converter (ADC) with various applications such as automotive, industrial, medical and consumer electronics. The working principle of the ADS1148IRHBR relies on a sigma-delta architecture which enables it to obtain high-precision and low-noise performance.
