DAC7563SQDGSRQ1

Digital To Analog Converters Overview

The DAC7563SQDGSRQ1 is a dual-channel, 12-bit digital-to-analog converter (DAC) from Texas Instruments, designed for automotive applications under the AEC-Q100 qualification standard. It features a resistor-string architecture with buffered voltage outputs and supports multiple serial interfaces including SPI, Microwire, and QSPI. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. Key performance metrics include a settling time of 10 µs, a power consumption of 500 µW, and an operating temperature range from -40°C to +125°C. Non-linearity specifications are defined by a maximum INL of ±0.3 LSB and DNL of ±0.05 LSB.

Digital To Analog Converters Feature Summary

• Integrated reset function to mid-scale output state
• Low-power operation with minimal current consumption
• Compact MSOP-10 package design for space-constrained layouts

Digital To Analog Converters Applications

• Automotive instrument clusters and display drivers
• Active noise cancellation systems in vehicles
• Industrial process control loops requiring high reliability
• Medical equipment signal conditioning circuits

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'SQDGS' corresponds to the MSOP-10 package and reel packaging configuration as listed in official distributor catalogs. Confirm AEC-Q100 certification status through the manufacturer's quality documentation. Ensure compatibility with existing board footprints by checking pin-out diagrams against the datasheet. Validate that the component meets RoHS compliance standards required for your region. Cross-reference the full part number to avoid confusion with non-automotive grade variants lacking the 'Q1' designation.

Digital To Analog Converters Selection Notes

Select this component when dual-channel precision is required within automotive thermal constraints. Compare against the DAC8563 if higher 16-bit resolution is necessary, noting the trade-off in speed and cost. Consider the DAC7562 if single-channel functionality suffices for the application. Evaluate interface compatibility with the host microcontroller to ensure support for SPI or Microwire protocols. Assess power budget requirements against the 500 µW typical consumption figure provided in the electrical characteristics table.

Digital To Analog Converters Part Context

This part belongs to the DAC7563 family of dual-channel DACs, which also includes non-automotive versions like the DAC7563SDGST. The 'Q1' suffix denotes automotive qualification, while 'SQDGS' specifies the MSOP-10 package and tape-and-reel shipping method. It shares architectural similarities with the DAC8563 but offers lower resolution optimized for cost-sensitive automotive environments. The family is characterized by low glitch impulse energy and fast settling times suitable for dynamic signal generation.

Digital To Analog Converters Replacement Considerations

Direct substitutes include the DAC7563SDGST for non-automotive use cases, though qualification differences exist. The DAC7562 series offers single-channel alternatives with identical electrical specifications. Verify pin compatibility before swapping with other MSOP-10 DACs from different manufacturers. Check if the DAC8563 provides sufficient headroom for future design iterations despite higher costs.
