AD7192 Datasheet PDF

●The AD7192BRUZ is a 24-bit Ultralow Noise Sigma-Delta (Σ-Δ) ADC with PGA for high precision measurement applications. It contains a low noise, 24-bit Sigma-Delta (Σ-Δ) analogue-to-digital converter (ADC). 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 AD7192 sequentially converts on each enabled channel. It 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 output data rate from the part can be varied from 4.7Hz to 4.8kHz. The complete analogue front end device has two digital filter options.
