DAC71416RHAR

Digital To Analog Converters Overview

The DAC71416RHAR is a 16-channel, 16-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 specifies monotonicity with a maximum integral nonlinearity (INL) of ±1 LSB at 16-bit resolution. The device supports flexible output configurations including bipolar ranges of ±2.5V to ±20V and unipolar ranges up to 40V. Each channel provides high drive capability with ±25mA absorption or sourcing. Communication is handled via a 4-wire SPI-compatible serial interface operating within a supply voltage range of 1.7V to 5.5V. The component is housed in a 40-pin VQFN package measuring 6mm x 6mm.

Digital To Analog Converters Feature Summary

• Integrated precision internal reference voltage source eliminates the need for external components in most applications
• Flexible output configuration allows independent programming of full-scale voltage ranges per channel
• High drive capability reduces the requirement for additional operational amplifiers
• Built-in power-on reset circuit ensures outputs remain grounded until proper configuration

Digital To Analog Converters Applications

• Optical module control systems
• Semiconductor test equipment
• Data acquisition systems requiring multi-channel high-voltage control

Digital To Analog Converters Procurement Notes

Verify the specific suffix RHAR against the manufacturer datasheet to confirm the tape-and-reel packaging option and temperature grade. Ensure compatibility with the required system voltage levels and interface protocols before ordering. Cross-reference the part number with official distributor catalogs to confirm current availability status and lead times.

Digital To Analog Converters Selection Notes

Select this component when multiple high-voltage analog outputs are required from a single IC. The 16-bit resolution and integrated reference suit applications demanding high accuracy without external calibration complexity. Consider the 40-pin VQFN footprint for space-constrained designs. Evaluate the ±25mA drive strength against load requirements to determine if additional buffering is necessary.

Digital To Analog Converters Part Context

This device belongs to the DACx1416 family, which includes pin-compatible variants with 12-bit (DAC61416) and 14-bit (DAC71416) resolutions. All members share the same functional architecture and package outline, allowing for design flexibility across different precision requirements while maintaining board layout consistency.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include the DAC61416 and DAC71416. These parts offer lower resolution but maintain identical physical dimensions and interface protocols. Verify that the reduced bit depth meets the application's accuracy specifications before substituting.
