GENERAL DESCRIPTION
The EV-AD74412RSDZ (see Figure 1) is a fully featured
evaluation board that can be used to evaluate the features of the
AD74412R. The
configurable, input/output device. The device has functionality
for analog output, analog input, digital input, and resistance
temperature detector (RTD) measurements integrated into a
single-chip solution with a serial peripheral interface (SPI)-
compatible interface.
The EV-AD74412RSDZ can be controlled via a system
demonstration platform (SDP). The
board allows the EV-AD74412RSDZ to be controlled via the
USB port of a PC using the
The EVAL- AD74412RSDZ requires an AVDD operating supply
of 14 V to 26.4 V. When the EV-AD74412RSDZ is connected to
the PC, the PC provides power to the
