AD7791BRMZ General Description

Compared to the AD7790, the AD7791 offers a higher resolution and improved performance. With a peak-to-peak resolution of 19 bits, equivalent to an effective resolution of 21.5 bits at the default output data rate of 16.6 Hz, the AD7791 ensures precise measurements and data analysis. Additionally, the option to enable or disable the buffer provides flexibility in signal processing and integration with other circuitry
