DAC71408RHAR

Digital To Analog Converters Overview

The DAC71408RHAR is an 8-channel, 14-bit high-voltage output digital-to-analog converter (DAC) from Texas Instruments. It features a buffered voltage output capable of driving up to ±25 mA. The device operates with a single analog supply voltage ranging from 4.5 V to 5.5 V and communicates via a 4-wire SPI-compatible serial interface supporting data rates up to 50 MHz. It includes an integrated low-drift 2.5 V internal reference source. The component is specified for operation over an extended temperature range of -40°C to +125°C and is housed in a 40-pin VQFN package measuring 6 mm by 6 mm.

Digital To Analog Converters Feature Summary

• Integrated precision internal reference source eliminates the need for external components in most applications
• Flexible output configuration supports multiple unipolar and bipolar voltage ranges per channel
• High drive capability allows direct connection to loads without additional operational amplifiers
• Dedicated pins enable generation of jitter signals for noise reduction in specific applications

Digital To Analog Converters Applications

• Optical network equipment requiring precise high-voltage control
• Industrial automation systems utilizing multi-channel signal generation
• Test and measurement instruments demanding high linearity and stability

Digital To Analog Converters Procurement Notes

Verify the complete part number including suffixes such as RHAR against official Texas Instruments documentation to ensure correct package type and tape-and-reel specifications. Confirm that the required operating temperature range and supply voltage levels align with the system design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when eight independent channels are required with high-voltage output capabilities and 14-bit resolution. Consider the DAC81408 if 16-bit resolution is necessary or the DAC61408 if 12-bit resolution suffices for cost optimization. Ensure the application benefits from the integrated reference and high current drive to simplify board layout.

Digital To Analog Converters Part Context

This device belongs to the DACx1408 family, which also includes the DAC81408 and DAC61408. These parts share pin compatibility and core functionality while differing primarily in resolution. The family is designed for applications requiring multiple high-voltage outputs with minimal external support circuitry.

Digital To Analog Converters Replacement Considerations

The DAC81408 and DAC61408 are pin-compatible alternatives within the same series. Verify that the resolution difference between 16-bit, 14-bit, and 12-bit variants meets the specific accuracy requirements of the target application.
