Product Description

The AD7194BCPZ is a 8-channel Ultralow Noise 24-bit 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 interface directly to the ADC. The device can be configured to have eight differential inputs or sixteen pseudo differential inputs. The on-chip channel sequencer allows several channels to be enabled simultaneously and the AD7194 sequentially converts on each enabled channel, simplifying 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 device has a very flexible digital filter, including a fast settling option. Variables such as output data rate and settling time are dependent on the option selected.
