DAC70508MYZFT

Digital To Analog Converters Overview

The DAC70508MYZFT is an octal, true 14-bit digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a serial Peripheral Interface (SPI) for data input and provides buffered voltage outputs. The device integrates a precision internal reference with an operating range of 1.2 V to 5.5 V. 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 electrical specifications include a settling time of 5 µs, a gain error of 0.14% FSR, and integral/differential nonlinearity of ±0.5 LSB. The component supports a sampling rate of 1 MS/s and consumes 33 mW of power. It functions within a temperature range of -40°C to +125°C and utilizes an R-2R architecture in a 16-DSBGA package.

Digital To Analog Converters Feature Summary

• Integrates a precision internal voltage reference to minimize external component requirements.
• Provides eight independent buffered voltage output channels for simultaneous signal generation.
• Supports high-speed serial communication via a standard SPI interface.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal conditioning.
• Programmable logic controller (PLC) analog output modules.
• Test and measurement equipment utilizing multi-channel signal generation.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'MYZFT' against official Texas Instruments documentation to confirm the exact package type and tape-and-reel configuration. Ensure compatibility with required supply voltage levels and SPI timing constraints before integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status.

Digital To Analog Converters Selection Notes

Select this component when eight synchronized 14-bit voltage outputs are required in a compact footprint. The integrated reference simplifies design compared to external reference solutions. Consider the DSBGA package constraints for thermal management and PCB layout. Verify that the 1 MS/s update rate meets the application's bandwidth requirements.

Digital To Analog Converters Part Context

This part belongs to the DACx0508 family of octal DACs, which includes variants with different resolutions such as the 12-bit DAC60508 and 16-bit DAC80508. The family shares common interfaces and architectures but varies in precision and performance metrics. The DAC70508 specifically targets applications needing a balance between resolution and speed.

Digital To Analog Converters Replacement Considerations

The DAC70508MRTET is a parameter-equivalent alternative offering the same 14-bit resolution and functionality in a WQFN package. Verify pinout compatibility and thermal characteristics when substituting between DSBGA and WQFN packages.
