DAC7644E/1K

Digital To Analog Converters Overview

The DAC7644E/1K is a precision, quad-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor ladder architecture to provide buffered voltage outputs with high linearity and low power consumption of 7.5 mW. The device features a parallel data interface and supports a supply voltage range of 4.75 V to 5.25 V for analog supplies. Key performance metrics include a settling time of 10 µs, a gain error of 0.08% FSR, and an operating temperature range from -40°C to +85°C. It is housed in a 48-pin SSOP package.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent 16-bit voltage outputs on a single integrated circuit.
• Parallel interface design enabling direct connection to microprocessors and digital control systems without serial protocol overhead.
• Integrated reset functionality allows all output channels to return to mid-scale simultaneously upon command.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable logic controller (PLC) analog output modules
• Test and measurement equipment needing precise multi-point voltage references

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details. The '/1K' designation typically indicates reel packaging, but datasheet confirmation is required to ensure compatibility with automated assembly processes and storage conditions.

Digital To Analog Converters Selection Notes

Select this component when a parallel interface is preferred over serial options like SPI or Microwire. It is suitable for applications requiring four synchronized 16-bit outputs with moderate speed requirements. Compare against the DAC7634E if a serial interface is acceptable to reduce pin count.

Digital To Analog Converters Part Context

This part belongs to the DAC7644 family of precision digital-to-analog converters. It serves as a higher-resolution alternative to the 12-bit DAC7615 series while offering a parallel interface distinct from the serial DAC7634 series. The device is designed for general-purpose analog signal generation in industrial environments.

Digital To Analog Converters Replacement Considerations

The DAC7644EB/1K is a verified substitute within the same family, differing primarily in packaging type rather than electrical function. Ensure pinout compatibility before substitution.
