DAC716U

Digital To Analog Converters Overview

The DAC716U is a monolithic 16-bit digital-to-analog converter manufactured by Texas Instruments in a 16-lead plastic SOIC package. It integrates a +10V temperature-compensated voltage reference, current-to-voltage amplifier, and high-speed synchronous serial interface with cascading capability via SDO. The device operates from ±11.4V to ±16.5V supplies, delivering a 0 to +10V output range. Key electrical parameters include a typical linearity error of ±2 LSB at +25°C and ±8 LSB over the –40°C to +85°C temperature range. Settling time is specified at 10µs for a 20V step and 4µs for a 1LSB step. The unit features an asynchronous clear function and TTL/CMOS compatible digital inputs.

Digital To Analog Converters Feature Summary

• Integrated precision internal voltage reference providing +10V output.
• High-speed synchronous serial interface supporting data cascading through SDO pin.
• Asynchronous clear function resets output voltage to zero immediately.
• External gain and offset adjustment pins allow calibration via potentiometers or external DACs.

Digital To Analog Converters Applications

• Precision industrial process control systems requiring high-resolution analog outputs.
• Multi-channel data acquisition systems utilizing cascaded serial bus configurations.
• Test and measurement equipment demanding low noise and monotonic performance.
• Instrumentation applications requiring isolated analog ground planes and precise signal generation.

Digital To Analog Converters Procurement Notes

Verify component authenticity and datasheet revision status prior to integration, as the DAC716U originates from the Burr-Brown portfolio acquired by Texas Instruments. Confirm that the specific ordering suffix matches the required temperature grade and packaging quantity. Ensure design compatibility with ±12V to ±15V supply rails and validate serial interface timing constraints against the host controller specifications.

Digital To Analog Converters Selection Notes

Select the DAC716U when a single-channel 16-bit resolution with integrated reference and buffered voltage output is required. This component is suitable for designs needing ±12V to ±15V dual supplies rather than single-supply operation. Consider the SOIC package dimensions and thermal characteristics for PCB layout. Evaluate the need for external gain/offset trimming capabilities if system accuracy requirements exceed the inherent ±2 LSB linearity specification.

Digital To Analog Converters Part Context

The DAC716U belongs to the DAC716 family of 16-bit digital-to-analog converters originally developed by Burr-Brown Corporation before its acquisition by Texas Instruments. The 'U' suffix specifically denotes the wide-body plastic SOIC package variant. Other family members include DIP packages (DAC716P) and different temperature grades such as the PK and UK variants. The device represents a legacy high-precision analog solution within TI's data converter portfolio.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers include DAC716UB and DAC716UG4. Verify pinout compatibility and electrical specifications against the target application requirements before substitution. Note that ordering suffixes may indicate variations in packaging or environmental compliance standards.

Digital To Analog Converters FAQ

How does the DAC716U handle multiple converter updates?

The DAC716U supports simultaneous updating of multiple converters through its double-buffered data latches and serial data output (SDO) pin, allowing cascaded connections on a common clock and data line.

What is the purpose of the Offset Adjust and Gain Adjust pins?

These pins allow for external calibration of the output transfer characteristic using potentiometers or external DACs, providing a minimum adjustment range of ±0.3% of Full Scale Range to correct for system-level errors.

Is the DAC716U monotonic over its full operating temperature range?

Yes, the DAC716U is guaranteed to be monotonic over the specified temperature range of –40°C to +85°C, ensuring stable analog output for increasing digital input codes.
