DAC7617E/1K

Digital To Analog Converters Overview

The DAC7617E/1K is a quad, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture with buffered voltage outputs and a serial interface compatible with standard SPI protocols. The device operates on a single 3.3V supply, consuming only 2.4mW of power. It provides a sampling rate of 89 kS/s per channel and achieves a settling time of 10 µs. Key accuracy specifications include a gain error of 0.2% FSR, integral nonlinearity of ±1 LSB, and differential nonlinearity of ±1 LSB. The component is housed in a 16-pin SOIC package and supports an industrial temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Quad-channel configuration delivering independent 12-bit resolution across four output channels.
• Integrated reset function that forces all outputs to mid-scale upon initialization or power-up.
• Low-power design optimized for battery-operated applications with minimal current consumption.
• Serial interface compatibility allowing direct connection to microcontrollers and DSPs.

Digital To Analog Converters Applications

• Portable instrumentation requiring multi-channel signal generation
• Battery-powered data acquisition systems
• Industrial process control loops
• Programmable voltage references

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade and '1K' denotes the reel packaging quantity of 1000 units. Confirm RoHS compliance status through the manufacturer's official documentation before finalizing procurement orders. Ensure the ordering part number matches the exact pinout and electrical characteristics required for the target application design.

Digital To Analog Converters Selection Notes

Select this component when a low-voltage, quad-channel DAC is required with high linearity and low power consumption. Compare against the DAC7616 series if a 5V supply is preferred, or the DAC7615 series for higher voltage ranges. Verify that the serial interface timing meets the system clock requirements and that the SOIC-16 package fits the available PCB footprint constraints.

Digital To Analog Converters Part Context

This part belongs to the DAC761x family of precision digital-to-analog converters. It shares architectural similarities with the DAC7614, DAC7615, and DAC7616 but is specifically optimized for 3.3V operation. The E variant extends the operating temperature range compared to commercial grade options, making it suitable for broader environmental conditions within the same package form factor.

Digital To Analog Converters Replacement Considerations

The DAC7616UB serves as a functional alternative if the system can accommodate a 3V to 3.6V supply range. The DAC7614E offers similar performance but typically requires a 5V supply. Verify pin compatibility and register mapping before substituting these parts in existing designs.
