AD5412AREZ

Digital To Analog Converters Overview

The AD5412AREZ is a single-channel, 12-bit digital-to-analog converter (DAC) from Analog Devices. It features a programmable current source and a buffered voltage output. The device operates with an AVDD supply range of 10.8 V to 40 V and AVSS from −26.4 V to 0 V. It includes an internal reference with a maximum drift of 10 ppm/°C and supports flexible serial interfaces including SPI and Microwire. Key specifications include ±0.01% FSR typical total unadjusted error, guaranteed monotonicity, and on-chip fault detection. The component is housed in a 24-lead TSSOP package.

Digital To Analog Converters Feature Summary

• Buffered voltage output ranges: 0 V to 5 V, 0 V to 10 V, ±5 V, or ±10 V
• On-chip fault detection for open circuits and overtemperature conditions

Digital To Analog Converters Applications

• Process controls
• Actuator controls
• PLC systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'AREZ' corresponds to the industrial temperature grade (-40°C to +105°C) and the TSSOP-24 package configuration as defined in the official ordering guide. Confirm that the required performance metrics align with the A-version accuracy specifications provided in the datasheet tables.

Digital To Analog Converters Selection Notes

Select this model when a 12-bit resolution is sufficient for the application requirements. Ensure the power supply architecture supports the specified AVDD and AVSS ranges. Note that HART connectivity requires the LFCSP package variant; the TSSOP version does not support this feature.

Digital To Analog Converters Part Context

The AD5412 is part of the AD5412/AD5422 family, which also includes the 16-bit AD5422. These devices are designed for industrial process control applications requiring high precision and flexibility in analog output configurations.

Digital To Analog Converters Replacement Considerations

The AD5422 offers identical pinout and functionality with 16-bit resolution. For lower cost requirements without voltage output needs, consider the AD5410 (12-bit current source only).

Digital To Analog Converters FAQ

Does the AD5412AREZ support HART communication?

No, HART connectivity is only available on the LFCSP package version of the AD5412/AD5422. The TSSOP package used by the AREZ suffix does not support this feature.

What is the maximum compliance voltage for the current output?

The current loop compliance voltage ranges from 0 V to AVDD minus 2.5 V.

Is the DAC guaranteed to be monotonic?

Yes, the AD5412 is guaranteed monotonic over its full operating temperature range with a DNL specification of -1 to +1 LSB.
