DAC7563TDSCT

Digital To Analog Converters Overview

The DAC7563TDSCT is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a serial interface compatible with standard DSP and SPI protocols, supporting data rates up to 100 kS/s per channel. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. It provides buffered voltage outputs with a typical settling time of 10 µs. Key accuracy specifications include an integral nonlinearity (INL) of ±0.3 LSB and a differential nonlinearity (DNL) of ±0.05 LSB. The component is housed in a 10-pin WSON package and is rated for operation over an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrated internal reference voltage source with low temperature coefficient
• Power-on reset circuit ensures output initialization to mid-scale
• Low power consumption suitable for battery-operated applications
• Glitch impulse filtering minimizes output transients during code changes

Digital To Analog Converters Applications

• Portable instrumentation systems requiring low power consumption
• Industrial process control loops utilizing 4-20 mA transmitter circuits
• Programmable gain amplifier biasing networks
• Battery-powered sensor signal conditioning modules

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'TD' indicates the inclusion of an internal reference voltage and 5V-tolerant I/O capabilities, distinguishing it from the base DAC7563SDSCT variant which may lack these features. Confirm the package type matches the design requirements, as the 'W' suffix typically denotes the WSON package while other suffixes may indicate different form factors. Ensure compatibility with the target system's voltage levels and thermal constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with integrated reference and high noise immunity is required. Compare against the DAC7562 series if lower cost is prioritized over the internal reference feature. Consider the DAC8563 series if higher 16-bit resolution is necessary for precision applications. Evaluate the power budget carefully, as the internal reference adds to the total quiescent current draw compared to external reference designs.

Digital To Analog Converters Part Context

This part belongs to the DAC756x family of dual-channel DACs from Texas Instruments. The family includes variants with and without internal references, such as the DAC7562 and DAC7563. The DAC7563 specifically integrates a 2.5 V reference, simplifying board layout and reducing component count. It shares pinout compatibility with other members of the series, facilitating design flexibility across product lines.

Digital To Analog Converters Replacement Considerations

The DAC7562TDSCT is a parameter-equivalent alternative within the same family. Verify if the internal reference requirement aligns with the application needs, as both parts share similar performance characteristics. Other family members like the DAC7563SDSCT serve as substitutes if the internal reference is not strictly required or if a different package option is preferred.
