DAC715U

Digital To Analog Converters Overview

The DAC715U is a monolithic 16-bit digital-to-analog converter manufactured by Texas Instruments in a 28-lead plastic SOIC package. It features a high-speed parallel double-buffered interface and an integrated +10V temperature-compensated reference. The device provides a voltage output range of 0 to +10V when powered by ±12V or ±15V supplies. Key electrical specifications include a settling time of 6µs for a 10V step, a maximum power dissipation of 600mW, and a signal-to-noise and distortion ratio (SINAD) of 87dB at a 100kHz sampling rate. The component operates within a temperature range of –40°C to +85°C.

Digital To Analog Converters Feature Summary

• Includes an internal +10V temperature-compensated voltage reference and current-to-voltage amplifier.
• Features a 16-bit parallel double-buffered data interface allowing simultaneous updates of multiple converters.
• Provides external gain and offset adjustment pins compatible with potentiometers or external D/A converters.
• Incorporates an asynchronous clear function that immediately sets the output voltage to half-scale.

Digital To Analog Converters Applications

• High-accuracy industrial process control systems requiring precise analog signal generation.
• Automatic calibration circuits utilizing the dedicated gain and offset adjustment capabilities.
• Multi-channel data acquisition systems benefiting from the double-buffered interface for synchronized updates.

Digital To Analog Converters Procurement Notes

Verify the specific performance grade required for the application, as linearity and monotonicity specifications vary across P, PB, PK, and PL grades. Confirm that the system design accommodates the necessary ±12V or ±15V dual supply rails and allows sufficient board space for the 28-lead SOIC package. Ensure proper grounding strategies are implemented to maintain the specified noise performance.

Digital To Analog Converters Selection Notes

Select the DAC715U when a 16-bit resolution with a unipolar 0 to +10V output range is required. Choose this component over lower-resolution devices if system accuracy demands a 1LSB value of approximately 152µV. Consider the available gain and offset trim ranges if external calibration is part of the manufacturing process. Verify that the host system can support the 16-bit parallel bus interface timing requirements.

Digital To Analog Converters Part Context

The DAC715U belongs to the Burr-Brown DAC715 family of precision digital-to-analog converters. This series is characterized by its complete monolithic integration of the DAC core, reference, and output amplifier. The U suffix specifically denotes the wide-body plastic SOIC package variant, which is recommended for new designs according to manufacturer documentation.

Digital To Analog Converters Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate other 16-bit parallel interface DACs from the manufacturer's portfolio if pin compatibility is not required.
