AD7193BCPZ-RL7

AD7193BCPZ-RL7 is a 4-channel, 4.8KHz, ultralow noise, 24-bit sigma-delta ADC with PGA. It is a low noise, complete analogue front end for high precision measurement applications. The on-chip low noise gain stage means that signals of small amplitude can interface directly to the ADC. This device can be configured to have four differential inputs or eight pseudo differential inputs. The on-chip channel sequencer allows several channels to be enabled simultaneously, and the device 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. It is used in applications such as PLC/DCS analogue input modules, data acquisition, strain gauge transducers, pressure measurement, temperature measurement, flow measurement, weigh scales, chromatography, medical and scientific instrumentation.
