Digital input

The AD74413R is a quad-channel software configurable

input/output solution for building and process control

applications. The AD74413R contains functionality for analog

output, analog input, digital input, resistance temperature

detector (RTD), and thermocouple measurements integrated

into a single chip solution with a serial peripheral interface (SPI).

The device features a 16-bit, Σ-Δ 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.

RTD measurement

There are several modes related to the AD74413R. 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.

Internal 16-bit, Σ-∆ ADC with optional 50 Hz and 60 Hz

rejection

13-bit monotonic DACs

Charge pump for true zero voltage output

HART-compatible

Internal temperature sensor, 5ꢀC accuracy

On-chip diagnostics including open circuit and short-circuit

detection

The AD74413R contains a high accuracy 2.5 V internal

reference to drive the DACs and the ADC.
