DAC715P

Digital To Analog Converters Overview

The DAC715P is a monolithic 16-bit digital-to-analog converter manufactured by Texas Instruments. It features a high-speed 16-bit parallel double-buffered interface and provides a voltage output range of 0 to +10V. The device integrates a temperature-compensated +10V reference, current-to-voltage amplifier, and an asynchronous clear function that sets the output to half-scale. It operates from ±12V or ±15V supplies with a maximum power dissipation of 600mW. The DAC715P is specified over a temperature range of –40°C to +85°C and is housed in a 28-lead plastic DIP package.

Digital To Analog Converters Feature Summary

• Features a high-speed 16-bit parallel double-buffered interface for simultaneous updates.
• Includes an integrated +10V temperature-compensated reference circuit.
• Provides external gain and offset adjustment capabilities for auto-calibration.
• Offers indefinite short-circuit protection on the analog output.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation.
• Automatic test equipment utilizing auto-calibration D/A converters.
• High-resolution data acquisition systems needing stable voltage outputs.

Digital To Analog Converters Procurement Notes

Verify the specific performance grade required for your application, as linearity specifications vary between grades P, PB, PK, and PL. Confirm that the system design accommodates the necessary dual supply voltages and ground separation techniques to maintain accuracy. Ensure proper handling procedures are followed due to electrostatic discharge sensitivity.

Digital To Analog Converters Selection Notes

Select the DAC715P when a complete 16-bit solution with an internal reference is needed. Choose this part if the application requires a 0 to +10V unipolar output swing driven by a standard 16-bit bus. Consider alternative grades such as DAC715PB or DAC715PL if tighter linearity errors are required within the same package form factor.

Digital To Analog Converters Part Context

The DAC715 series was originally developed by Burr-Brown Corporation before being acquired by Texas Instruments. The component represents a legacy high-performance D/A converter designed for applications demanding high accuracy and fast settling times without external reference components.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers include DAC715U (SOIC package), DAC715PB (higher linearity DIP), DAC715UB (higher linearity SOIC), DAC715PK (commercial temp DIP), DAC715UK (commercial temp SOIC), DAC715PL (highest linearity DIP), and DAC715UL (highest linearity SOIC).

Digital To Analog Converters FAQ

What input coding does the DAC715P support?

The DAC715P is designed to accept binary two's complement (BTC) input codes.

How does the asynchronous clear function operate?

Asserting the CLR input low immediately resets both the input latch and the D/A latch to code 0000H, setting the analog output to half-scale (5V).

Can the DAC715P be operated in single-buffered mode?

Yes, by connecting A0 and A1 to digital ground (DCOM) and ensuring the write pulse width is at least 80ns, the interface acts as a transparent single buffer.
