DAC7734EC

Digital To Analog Converters Overview

The DAC7734EC is a 16-bit, quad voltage output digital-to-analog converter manufactured by Burr-Brown. It features four independent channels with parallel word input and internal double-buffered DAC logic for synchronous updates. The device supports both unipolar (+10 V) and bipolar (±10 V) single or dual supply operation. Key electrical characteristics include a maximum settling time of 10 μs to 0.003% accuracy and guaranteed 16-bit monotonicity over the specified temperature range. It operates within an industrial temperature range of -40 °C to +85 °C.

Digital To Analog Converters Feature Summary

• Four independent 16-bit voltage output channels
• Internal double-buffered DAC logic for synchronized multi-channel updates
• Programmable asynchronous reset to mid-scale or zero scale
• Internal data back-read mode for input register verification

Digital To Analog Converters Applications

• Industrial process control systems requiring precise multi-channel analog outputs
• Data acquisition systems needing high-resolution signal generation
• Test and measurement equipment requiring stable, low-noise voltage references

Digital To Analog Converters Procurement Notes

Verify the specific suffix code against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with existing parallel interface timing requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Confirm availability of the original Burr-Brown part number versus Texas Instruments equivalents.

Digital To Analog Converters Selection Notes

Select this component when four isolated 16-bit outputs are required in a single package. Consider the parallel interface complexity versus serial alternatives like SPI-based DACs. Evaluate power consumption needs as the device dissipates approximately 200 mW. Verify that the ±10 V or +10 V output swing matches the downstream circuit requirements without additional amplification.

Digital To Analog Converters Part Context

The DAC7734EC belongs to the Burr-Brown DAC77xx family of precision digital-to-analog converters. This series is designed for applications demanding high linearity and stability. The device integrates reference buffers and output amplifiers, reducing external component count compared to discrete solutions.
