DAC7568IAPWR

Digital To Analog Converters Overview

The DAC7568IAPWR is an octal-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a 2.5V internal reference with 2ppm/°C temperature coefficient and supports SPI-compatible serial interfaces. The device operates on a single supply voltage ranging from 2.7V to 5.5V for both analog and digital domains. It utilizes a TSSOP-38 package and provides buffered voltage outputs for each channel. The component is designed for applications requiring low glitch energy and high channel density in compact form factors.

Digital To Analog Converters Feature Summary

• Integrates eight independent 12-bit DAC channels within a single compact package
• Includes a precision 2.5V internal voltage reference with low temperature drift
• Provides buffered voltage outputs to drive external loads directly
• Supports standard SPI-compatible serial communication interfaces

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation utilizing battery-powered single-supply operation
• Data acquisition systems needing synchronized analog output updates
• Automotive electronic modules demanding robust voltage regulation

Digital To Analog Converters Procurement Notes

Verify the specific suffix IAPWR against official datasheets to confirm the TSSOP-38 package type and industrial temperature range specifications. Ensure compatibility with system power supplies operating between 2.7V and 5.5V. Confirm that the required serial interface timing aligns with the device's maximum clock rates. Check for moisture sensitivity levels if reflow soldering is planned.

Digital To Analog Converters Selection Notes

Select this component when eight simultaneous analog outputs are necessary without external multiplexing. The integrated reference eliminates the need for external precision voltage sources, reducing board space. Consider the TSSOP-38 footprint constraints during PCB layout. Verify that the 12-bit resolution meets the application's accuracy requirements compared to higher-resolution alternatives like the DAC8168 or DAC8568.

Digital To Analog Converters Part Context

This part belongs to the DAC7568 family of octal-channel converters from Texas Instruments. It shares architectural similarities with the DAC8168 and DAC8568, differing primarily in resolution and reference characteristics. The series is designed for cost-sensitive applications requiring multiple channels in a small outline package. It complements other data converter products in the manufacturer's portfolio for complete signal chain solutions.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible substitutes include the DAC8168IAPWR and DAC8568IAPWR, which offer higher resolutions but may require software adjustments for different full-scale ranges. Verify thermal performance and power consumption differences when upgrading to these variants.
