DAC70508ZRTER

Digital To Analog Converters Overview

The DAC70508ZRTER is an octal, true 14-bit voltage-output digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a serial peripheral interface (SPI) and integrates a precision internal reference. The device utilizes an R-2R architecture with buffered outputs, supporting a sampling rate of 1 MS/s and a typical settling time of 5 µs. It operates on analog supply voltages from 2.7 V to 5.5 V and digital supply voltages from 1.7 V to 5.5 V. Key performance metrics include a gain error of 0.14% FSR, and integral/differential nonlinearity of ±0.5 LSB. The component is housed in a 16-WQFN package and functions within a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates a precision internal reference source for simplified system design.
• Provides eight independent voltage-buffered output channels.
• Supports high-speed serial communication via SPI interface.
• Includes a reset function to initialize outputs to mid-scale.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation.
• Programmable power supply architectures.
• Test and measurement equipment needing precise voltage references.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'RTER' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-WQFN footprint matches the target PCB layout dimensions. Ensure compatibility with the intended SPI clock speeds and voltage levels before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when eight synchronized 14-bit voltage outputs are necessary within a compact form factor. The integrated reference eliminates external calibration needs, while the wide operating temperature range supports harsh industrial environments. Compare against the DAC70508MRTET if alternative packaging or availability constraints exist.

Digital To Analog Converters Part Context

This part belongs to the DAC70508 family of octal DACs from Texas Instruments. The series is designed for applications demanding high channel count and precision in limited space. The ZRTER designation specifically identifies the WQFN-16 package variant with reel packaging, distinguishing it from cut-tape or other package options within the same product line.

Digital To Analog Converters Replacement Considerations

The DAC70508MRTER is documented as a parameter-equivalent substitute. Verify pinout and electrical specifications match the original design requirements before substitution.
