GENERAL DESCRIPTION

The EVAL-AD74115H-ARDZ is a fully featured evaluation board

that can be used to evaluate the features of the AD74115H in a

full system solution where power and isolation are provided by the

ADP1034. 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.
