DAC725KP

Digital To Analog Converters Overview

The DAC725KP is a dual 16-bit digital-to-analog converter manufactured by Texas Instruments. It features an internal reference and output op amps, designed for ±10V bipolar voltage outputs. The device supports serial or parallel data input via an 8-bit microprocessor bus interface. Key electrical specifications include a linearity error of ±0.006% of full-scale range (FSR) and 14-bit monotonicity over the specified temperature range. It operates with +VCC and -VCC supplies between ±11.4V and ±16.5V, and a VDD logic supply of +4.5V to +5.5V. The component is housed in a 28-pin plastic DIP package.

Digital To Analog Converters Procurement Notes

Verify the current marketing status before design implementation. The datasheet indicates this part may be classified as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors and ensure the specific lot matches the required accuracy grade. Check for updated lifecycle notices from the manufacturer.

Digital To Analog Converters Selection Notes

Select the DAC725KP when high precision and dual-channel isolation are required. Ensure the system can accommodate the specified ±15V analog supply rails and +5V logic supply. Verify that the 28-pin PDIP footprint fits the PCB layout constraints. Consider external trimming if tighter gain and offset adjustments are needed beyond factory calibration.

Digital To Analog Converters Part Context

This component belongs to the DAC725 family of dual 16-bit converters produced by Burr-Brown, now part of Texas Instruments. It is distinct from other DAC models by its hybrid construction which minimizes digital feedthrough. The KP suffix denotes a specific accuracy grade compared to the JP variant.

Digital To Analog Converters Replacement Considerations

The DAC725JP is a similar model within the same family but offers a higher maximum linearity error specification. No direct modern replacements are listed in the provided documentation.
