The AD74412R is a quad-channel software configurable input/output solution for building and process control applications. The AD74412R contains functionality for analog output, analog input, digital input, and resistance temperature detector (RTD) measurements integrated into a single chip solution with an interface compatible with the serial port interface (SPI).

The device features a 16-bit, Σ-∆ analog-to-digital converter (ADC) and four configurable, 13-bit digital-to-analog converters (DACs) to provide four configurable input/output channels and a suite of diagnostic functions.

There are several modes related to the AD74412R. These modes are voltage output, current output, voltage input, externally powered current input, loop powered current input, external RTD measurement, digital input logic, and loop powered digital input.

The AD74412R contains a high accuracy 2.5 V internal reference to drive the DACs and the ADC.

Product Highlights

  1. Quad-Channel, Software Configurable Channels.
  2. Built In Diagnostics and Alert Features.
  3. Robust Architecture. Surge tested to ±1 kV, per the IEC61000-4-5 standard, on the input/output terminals with unshielded cables.

Features and Benefits

  • Fully featured evaluation board for the AD74412R
  • On-board 2.5 V ADR4525 reference
  • SPI
  • PC-based software for control

Product Detail

The EV-AD74412RSDZ (see Figure 1) is a fully featured evaluation board that can be used to evaluate the features of the AD74412R. The AD74412R is a quad-channel, software 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 EVAL-SDP-CS1Z (SDP-S) board allows the EV-AD74412RSDZ to be controlled via the USB port of a PC using the AD74412R evaluation software. 

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 SDP-S board. 

For full details on the AD74412R, see the AD74412R data sheet, which must be consulted in conjunction with this user guide when using the EV-AD74412RSDZ.
