The AD74115H is a single-channel, software configura- ble, input and output device. The device has functionality for analog output, analog input, digital input, digital output, and 2-wire, 3-wire, and 4-wire resistance temperature detector (RTD) measurements integrated into a single-chip solution with a compatible serial periph- eral interface (SPI). The EVAL-AD74115H-ARDZ can be controlled via a system dem- onstration platform (SDP) board. The EVAL-SDP-CK1Z (SDP-K1) board allows the EVAL-AD74115H-ARDZ to be controlled via the USB port of a PC using the AD74115H evaluation software. The EVAL-AD74115H-ARDZ requires an operating supply of 4.5 V to 60 V. The PC provides power to the SDP-K1 board. For full details on the AD74115H and ADP1034, see the AD74115H and ADP1034 data sheets, which must be consulted in conjunction with this user guide when using the EVAL-AD74115H-ARDZ.
