DAC7617U

Digital To Analog Converters Overview

The DAC7617U is a quad, serial input, 12-bit voltage output digital-to-analog converter manufactured by Burr-Brown. It features four independent R-2R ladder DACs with on-chip output amplifiers capable of rail-to-rail swing. The device operates from a single 3V to 3.6V supply and consumes low power, typically 2.4mW. Key electrical parameters include a settling time of 10µs, a sampling rate of 89kS/s per channel, and integral/differential nonlinearity of ±1 LSB. It utilizes a standard 3-wire serial interface compatible with SPI and QSPI modes.

Digital To Analog Converters Feature Summary

• Process control loops requiring multi-channel analog output
• Industrial automation signal generation

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation as Burr-Brown or Texas Instruments, as Burr-Brown was acquired by TI. Confirm the package type is SOIC-16 and check for RoHS compliance status in the specific datasheet revision. Ensure the ordering suffix matches the required temperature range and packaging format.

Digital To Analog Converters Selection Notes

Select this component when four independent 12-bit voltage outputs are required in a compact form factor. It is suitable for designs needing low power consumption and a simple serial interface. Compare against the DAC7616 if unbuffered outputs are acceptable, or the DAC7615 if higher speed is needed. Verify that the 3.3V logic levels match the system microcontroller.

Digital To Analog Converters Part Context

The DAC7617U belongs to the DAC761x family of quad 12-bit DACs from Burr-Brown. It shares pinout compatibility with other members like the DAC7616 and DAC7615, differing primarily in output buffer specifications and speed. This series is designed for general-purpose analog output applications requiring multiple channels.

Digital To Analog Converters Replacement Considerations

The DAC7616U is a direct pin-compatible alternative with unbuffered outputs. The DAC7615U offers faster conversion speeds but may have different power characteristics. Verify electrical parameter overlaps before substitution.
