DAC61416RHAT

Digital To Analog Converters Overview

The DAC61416RHAT is a 16-channel, 12-bit high-voltage output digital-to-analog converter (DAC) manufactured by Texas Instruments. It features an integrated low-drift 2.5V internal reference voltage source and buffered outputs capable of sourcing or sinking up to 25mA. The device supports flexible output configurations including ±20V, ±10V, ±5V, ±2.5V bipolar ranges and 0V to 40V unipolar ranges. Communication is handled via a 50MHz SPI-compatible serial interface with CRC error checking. It 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 reel packaging format as indicated in distributor listings. Confirm RoHS compliance status through official documentation. Ensure the ordering part number matches the required 12-bit resolution variant distinct from the 14-bit and 16-bit versions in the same family.

Digital To Analog Converters Selection Notes

Select this component when a high channel count with independent high-voltage control is required. The 12-bit resolution offers a balance between cost and performance compared to the 14-bit and 16-bit variants. Consider the integrated reference and drive strength to minimize external component count in designs requiring ±20V or 40V outputs.

Digital To Analog Converters Part Context

This device belongs to the DACx1416 series, which includes pin-compatible 12-bit (DAC61416), 14-bit (DAC71416), and 16-bit (DAC81416) models. All variants share the same functional architecture and package, differing primarily in resolution and associated accuracy specifications such as integral nonlinearity.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include the DAC71416RHAT for 14-bit resolution and the DAC81416RHAT for 16-bit resolution. These parts maintain identical functionality and pinouts while offering higher precision.
