Product Details

The EVAL-AD74115-ARDZ is a fully featured evaluation board that can be used to evaluate the features of the AD74115 in a full system solution where power and isolation are provided by the ADP1034. The AD74115 is a single-channel, software configurable, input and output device. The device has functionality for analog output, analog input, digital input, digital output, thermocouple measurement, and 2-wire, 3-wire, and 4-wire resistance temperature detector (RTD) measurements integrated into a single-chip solution with a compatible serial peripheral interface (SPI).

The EVAL-AD74115-ARDZ can be controlled via a system demonstration platform (SDP) board. The EVAL-SDP-CK1Z (SDP-K1) board allows the EVAL-AD74115-ARDZ to be controlled via the USB port of a PC using the AD74115 evaluation software. The EVAL-AD74115-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 AD74115 and ADP1034, see the AD74115 and ADP1034 data sheets, which must be consulted in conjunction with the user guide when using the EVAL-AD74115-ARDZ.
