DAC716UB/1K

Digital To Analog Converters Overview

The DAC716UB/1K is a monolithic 16-bit digital-to-analog converter manufactured by Texas Instruments. It integrates a precision internal voltage reference, current-to-voltage amplifier, and high-speed synchronous serial interface with cascading capability. The device provides a unipolar output voltage range of 0 to +10V when powered by ±12V to ±15V supplies. Key electrical specifications include a typical linearity error of ±2 LSB, a settling time of 6 μs for a 20V step, and an output noise spectral density of 120 nV/√Hz. It operates within a temperature range of –40°C to +85°C and is housed in a 16-lead plastic SOIC package.

Digital To Analog Converters Feature Summary

• Integrates a precision internal +10V temperature-compensated voltage reference and current-to-voltage amplifier.
• Features a double-buffered synchronous serial interface allowing simultaneous updates of multiple converters via cascaded connections.
• Includes an asynchronous clear function that immediately resets the output voltage to zero.
• Provides external gain and offset adjustment pins for calibration using potentiometers or external DACs.

Digital To Analog Converters Applications

• High-resolution data acquisition systems requiring precise analog signal generation.
• Industrial process control loops utilizing serial communication buses.
• Test and measurement equipment needing low-noise voltage references.
• Automotive electronic control units operating in extended temperature environments.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and reel quantity. Ensure the design supports the required dual supply voltages of ±12V to ±15V. Confirm that the serial interface timing meets the system clock requirements. Check for any recent lifecycle status changes such as NRND or Obsolete classifications before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component for applications demanding 16-bit resolution with integrated reference capabilities. Consider the ±2 LSB linearity error and 120 nV/√Hz noise performance for precision requirements. Evaluate the need for external gain and offset adjustments if higher accuracy than factory trim is required. Ensure the PCB layout accommodates separate analog and digital ground planes to minimize interference.

Digital To Analog Converters Part Context

This part belongs to the DAC716 family of 16-bit digital-to-analog converters. It shares functional similarities with other Burr-Brown derived devices but is distinguished by its specific serial interface configuration and integrated reference. The UB suffix denotes the plastic SOIC package variant specified for the industrial temperature range.

Digital To Analog Converters Replacement Considerations

Direct replacements must match the 16-bit resolution, serial interface protocol, and ±15V supply requirements. Verify pin compatibility for the 16-lead SOIC package. Note that newer generations may offer improved linearity or lower power consumption but might require software or hardware modifications.
