DAC7564IAPW

Digital To Analog Converters Overview

The DAC7564IAPW is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes a resistor-string architecture and features buffered voltage outputs. The device supports multiple serial interfaces including SPI, DSP, Microwire, and QSPI. It 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, an integral nonlinearity (INL) of ±0.5 LSB, and a differential nonlinearity (DNL) of ±0.1 LSB. The gain error is specified at 0.2% FSR, with a typical power consumption of 2.9 mW. It functions within a temperature range of -40°C to +105°C and is housed in a 16-pin TSSOP package.

Digital To Analog Converters Feature Summary

• Quad-channel configuration with independent 12-bit resolution per channel
• Integrated output buffers for direct drive capability
• Flexible serial interface compatibility with standard communication protocols
• Low power operation suitable for battery-powered applications

Digital To Analog Converters Applications

• Portable instrumentation systems requiring multi-channel signal generation
• Industrial process control loops needing precise voltage references
• Data acquisition systems utilizing external or internal voltage references
• Programmable gain amplifier biasing circuits

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'IAPW' against the manufacturer's current datasheet to confirm the industrial temperature grade and tube packaging details. Ensure that the required serial protocol mode matches the system controller's capabilities, as the device supports multiple interface standards. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Digital To Analog Converters Selection Notes

Select this component when four independent 12-bit channels are required in a compact surface-mount package. Consider the DAC7564 over higher-resolution alternatives if cost and power consumption are primary constraints while maintaining adequate linearity. Verify that the 2.7 V minimum supply voltage aligns with the system's available power rails and that the 10 µs settling time meets the application's update rate requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC7564 family of low-power, 12-bit digital-to-analog converters. It shares architectural similarities with other members like the DAC7565 and DAC7568, differing primarily in channel count and specific interface configurations. The IAPW designation indicates an industrial temperature range variant packaged in a TSSOP-16 form factor, distinct from automotive or extended commercial grades.

Digital To Analog Converters Replacement Considerations

DAC7564ICPW: Same family member with potentially different temperature or packaging specifications; verify suffix details. DAC7564IAPWR: Reel-packaged version of the same electrical specification; check availability and reel size requirements.
