DAC70508MRTER

Digital To Analog Converters Overview

The DAC70508MRTER is an octal, true 14-bit SPI voltage-output digital-to-analog converter manufactured by Texas Instruments. It features a compact 16-WQFN (3x3 mm) package with exposed thermal pad for surface-mount installation. The device operates on analog supply voltages ranging 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 typical settling time of 5 µs, a power consumption of 33 mW, and a working supply current of 5 mA. Nonlinearity performance is specified at ±0.5 LSB for both integral and differential errors, with a gain error of 0.14% FSR. The operating temperature range extends from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates eight independent 14-bit channels within a single small-footprint package.
• Utilizes R-2R architecture to deliver buffered voltage outputs via a standard SPI interface.
• Includes internal reset functionality to initialize outputs to mid-scale upon power-up.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable logic controller (PLC) analog output modules
• Test and measurement equipment needing precise multi-point voltage references

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'MR' against design requirements, as it denotes a distinct material or processing specification compared to other variants like 'ZR'. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) prior to PCB assembly planning. Ensure ordering quantities align with manufacturer standard packaging configurations to avoid handling discrepancies during procurement.

Digital To Analog Converters Selection Notes

Select this component when eight synchronized 14-bit channels are required in a space-constrained design. The R-2R architecture offers a balance between speed and linearity suitable for general-purpose applications. Compare against the DAC70508ZRTER if different material specifications are mandated, noting that pinouts remain compatible across the family while internal construction may vary.

Digital To Analog Converters Part Context

This part belongs to the DAC70508 family of octal DACs from Texas Instruments. It shares architectural similarities with the DAC70504 (quad channel) and DAC60508 (12-bit resolution). The device complements the DAC80508 series but provides lower resolution with optimized power characteristics for cost-sensitive industrial applications.

Digital To Analog Converters Replacement Considerations

DAC70508MRTET is listed as a parameter-equivalent alternative. Verify package tape-and-reel specifications and ensure functional compatibility before substitution.
