-The MicroZed board doesn't incorporate an ADC. Please refer to [[embedded_systems:experimentiersystem:expmicrozed|Adapter for Microzed Board]] for connecting an external ADC128S102 (general purpose, 8 channels) or a AD7476 (1 channel, for IR distance sensors). The electrical specifications are determined by the external circuitry of the ADCs.
+The Zynq7000 processor incorporates an ADC (XADC). In order to use this XADC, you have to choose the appropriate [[embedded_systems:zynq7000:microzed#configuration_files|Configuration File]]. When measuring unipolar analog input signals, the differential analog inputs (VP
+and VN) have an input range of 0V to 1.0V. The voltage on VP (measured with
+respect to VN) must always be positive. VN is typically connected to a local ground. Because the differential input range is from 0V to 1.0V (VP to VN), the maximum signal on VP is 1.0V.
+WARNING For interconnections to other devices such as sensors you have to strictly adhere to the maximum voltage allowed.
+You can also connect an external ADC128S102 (general purpose, 8 channels) or a AD7476 (1 channel, for IR distance sensors). Please refer to [[embedded_systems:experimentiersystem:expmicrozed|Adapter for Microzed Board]] for proper connections. The electrical specifications are determined by the external circuitry of the ADCs.
