Analog Devices Inc. Quad-Channel Software Configurable I/O

Analog Devices AD74412R Quad-Channel Software Configurable I/O is for use in building control systems, process control, and industrial automation. The four channels of the AD74412R can be configured for voltage/current input or output, digital input, or RTD measurements.

The device features a 16-bit delta-sigma ADC, and one 13-bit monotonic DAC for each channel. On-chip diagnostics and alert features include open and short detection and a temperature sensor. The ADC and DACs can use an external reference or the high accuracy 2.5V internal reference, and the device has an internal charge pump that enables a true 0V output. 

The AD74412R is designed with robust architecture to use in noisy environments and withstand overvoltage events.

• Six configurable modes: voltage input, current input, voltage output, current output, digital input, RTD measurement
• Internal 16-bit Σ-∆ ADC
  • Optional 50 Hz and 60 Hz rejection
• Four 13-bit monotonic DACs
  • One per channel
• On-chip diagnostics and alerts
  • Open and short circuit detection
  • Internal temperature sensor, 5°C accuracy
• ADC and DACs driven with external or internal reference
  • Integrated 2.5V high-accuracy reference
• Robust architecture for use in noisy environments
  • Surge tested to ±1 kV, per IEC61000-4-5
