4、o evaluate the features of the AD74413R.The AD74413R is a quad-channel, software configurable, inputand output device. The device has functionality for analog output,analog input, digital input, and resistance temperature detector（RTD） measurements integrated into a single chip solutionwith a serial

5、 peripheral interface （SPI）.The EV-AD74413RSDZ can be controlled via a systemdemonstration platform （SDP）. The SDP-S controls the EVAD74413RSDZvia the USB port of a PC using the AD74413R evaluation software.The EV-AD74413RSDZ requires an AVDD operating supply of14 V to 28.8 V. When the EV-AD74413RSD

6、Z is connected to thePC, the PC powers the SDP-S.See the AD74413R data sheet for more information about theAD74413R, and users must consult the data sheet in conjunctionwith this user guide when using the EV-AD74413RSDZ.评估板EV-AD74413RSDZ主要特性:Fully featured evaluation board for the AD74413ROn-board 2
