DAC7617U/1KG4

Digital To Analog Converters Overview

The DAC7617U/1KG4 is a quad, serial input, 12-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It operates from a single +3V supply and features guaranteed 12-bit monotonicity over the -40°C to +85°C temperature range. The device utilizes an R-2R ladder architecture with double-buffered data inputs for simultaneous updates. Key electrical parameters include a settling time of 10 μs to 0.012%, power dissipation of 3 mW, and linearity errors of ±1 LSB (UB grade). It is housed in a 16-pin SOIC package.

Digital To Analog Converters Feature Summary

• Quad-channel architecture with independent R-2R ladder networks and output operational amplifiers sharing common reference inputs.
• Double-buffered serial interface allows new data entry without disturbing analog outputs, enabling simultaneous multi-channel updates via LDAC.
• Asynchronous reset function clears all registers to zero-scale or mid-scale based on the RESETSEL pin configuration.

Digital To Analog Converters Applications

• Process control systems
• Automatic test equipment (ATE) pin electronics
• Closed-loop servo-control applications
• Motor control circuits
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and linearity grade. The '/1K' designation indicates tape and reel packaging containing 1000 devices per reel. Ensure compatibility with system voltage levels and timing requirements before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a low-power, single-supply solution is required for multi-channel signal generation. Compare the UB variant for tighter linearity specifications if higher precision is needed. Verify that the serial interface timing meets the host controller's capabilities and that the SOIC-16 footprint fits the PCB layout constraints.

Digital To Analog Converters Part Context

This part belongs to the DAC7617 family of quad 12-bit DACs. It shares architectural similarities with the DAC7615 and DAC7616 but differs in supply voltage requirements and specific linearity grades. The U package denotes the SOIC-16 form factor, distinguishing it from the SSOP-20 E package variants within the same product series.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other members of the DAC761x family such as the DAC7615U or DAC7616U, provided supply voltage and linearity requirements are met. Cross-referencing pinouts and serial interface protocols is essential when replacing with components from different manufacturers.
