The EVAL-AD7194EBZ is a fully featured evaluation board for the AD7194, 24bit sigma delta analogue to digital converter (ADC). The AD7194 is a low noise, complete analogue front end for high precision measurement applications. The device can be configured to have eight differential inputs or sixteen pseudo differential inputs. The onchip 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. This evaluation board can be connected to a PC via a standard USB interface. Software is provided enabling the user to perform detailed analysis of the ADC's performance.
