DAC71416RHAT

Digital To Analog Converters Overview

The DAC71416RHAT is a 16-channel, 14-bit digital-to-analog converter (DAC) from the DACx1416 series by Texas Instruments. It features an integrated low-drift 2.5V internal reference voltage source and high-voltage output buffers capable of sourcing or sinking up to 25mA. The device supports flexible output configurations including ±20V, ±10V, ±5V, ±2.5V bipolar ranges and 40V, 20V, 10V, 5V unipolar ranges. It utilizes a 4-wire serial interface compatible with 1.7V to 5.5V logic levels and includes on-chip offset and gain calibration. The component operates within a temperature range of -40°C to +125°C and is housed in a 40-pin VQFN package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix RHAT corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the 14-bit resolution variant aligns with system accuracy requirements compared to the 12-bit or 16-bit counterparts in the same family. Ensure compatibility with the 4-wire serial communication protocol used by the host microcontroller or FPGA before finalizing procurement specifications.

Digital To Analog Converters Selection Notes

Select this model when a balance between channel count and resolution is required for high-voltage applications. The 14-bit resolution offers sufficient precision for many industrial controls while reducing complexity compared to 16-bit variants. Consider the integrated reference and calibration features if external precision components are undesirable. Verify that the 40-VQFN package footprint fits the PCB layout constraints and thermal management requirements of the target design.

Digital To Analog Converters Part Context

This component belongs to the DACx1416 family, which includes pin-compatible 12-bit (DAC61416), 14-bit (DAC71416), and 16-bit (DAC81416) versions. All members share the same 40-pin VQFN package and core architecture but differ in resolution and associated performance metrics such as integral nonlinearity. This specific part provides mid-range resolution within the series.

Digital To Analog Converters Replacement Considerations

Direct substitutes include DAC61416RHAT for lower resolution needs and DAC81416RHAT for higher precision requirements. Both share identical pinouts and software compatibility. For legacy replacements, verify if older DAC714 variants meet the updated voltage and speed specifications.
