AD7190BRUZ Datasheet PDF - ADI

●The AD7190BRUZ is an ultralow noise 24-bit sigma-delta Analog-to-digital Converter (ADC) with PGA. The on-chip low noise gain stage means that signals of small amplitude can be interfaced directly to the ADC. The device can be configured to have two differential inputs or four pseudo differential inputs. The on-chip channel sequencer allows several channels to be enabled and the converter sequentially converts on each enabled channel. This simplifies communication with the part. The on-chip 4.92MHz clock can be used as the clock source to the ADC or alternatively an external clock or crystal can be used. The device has two digital filter options. The choice of filter affects the rms noise/noise-free resolution at the programmed output data rate, the settling time and the 50/60Hz rejection.
