DAC70508ZRTET

Digital To Analog Converters Overview

The DAC70508ZRTET is an octal, true 14-bit digital-to-analog converter manufactured by Texas Instruments. It features a high-speed R-2R architecture with a typical settling time of 5 µs and supports data rates up to 1 MS/s. The device integrates a precision internal reference and provides buffered voltage outputs on all eight channels. It operates with analog supply voltages ranging from 2.7 V to 5.5 V and digital supplies from 1.7 V to 5.5 V. Key performance metrics include ±0.5 LSB INL/DNL accuracy and a gain error of 0.14% FSR. The component is housed in a compact 16-WQFN (3x3 mm) package and functions within a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates a precision internal reference voltage source to minimize external component count.
• Provides fully buffered voltage outputs for direct driving of downstream loads.
• Supports standard SPI interface for straightforward digital control and configuration.
• Features a reset function to initialize outputs to mid-scale upon power-up.

Digital To Analog Converters Applications

• Process control systems requiring multi-channel signal generation
• Industrial automation and instrumentation
• Medical equipment signal processing
• Test and measurement devices

Digital To Analog Converters Procurement Notes

Verify the specific suffix ZRTET to confirm the 16-WQFN package and tape-and-reel packaging format. Ensure compatibility with the target system's SPI protocol and voltage levels. Confirm that the operating temperature range meets environmental requirements. Check RoHS compliance status if restricted substances are a constraint. Validate pinout alignment during PCB layout to ensure correct soldering and electrical connection.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated or coupled analog outputs are required from a single controller. The integrated reference simplifies design compared to external reference solutions. Consider the 16-WQFN footprint for space-constrained boards. Evaluate power consumption against system thermal limits, noting the 33 mW typical dissipation. Compare settling time specifications against application bandwidth requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC70508 family of octal DACs from Texas Instruments. It shares architectural similarities with other members like the DAC70508MRTER but differs in packaging and reel specifications. The family is designed for applications needing high channel density and precision in a small form factor. It complements Texas Instruments' broader portfolio of data converters.

Digital To Analog Converters Replacement Considerations

The DAC70508MRTET is documented as a parameter-equivalent alternative. Verify pinout and package dimensions before substitution. Other family members may offer different resolutions or channel counts.
