How should I properly supply power to the DAC813?

Click For Summary
SUMMARY

The DAC813 requires a positive supply of +15 V connected to pin 8 (+Vcc) and a negative supply of -15 V connected to pin 10 (-Vcc). The documentation specifies that both supplies are necessary for proper operation. Additionally, pins 5 and 16 must be grounded to ensure the device functions correctly. Misunderstanding the power supply requirements can lead to improper functionality of the DAC813.

PREREQUISITES
  • Understanding of DAC (Digital-to-Analog Converter) operation
  • Familiarity with power supply configurations for electronic components
  • Knowledge of Texas Instruments DAC813 specifications
  • Basic electronics knowledge, including grounding techniques
NEXT STEPS
  • Review the Texas Instruments DAC813 datasheet for detailed specifications
  • Learn about proper grounding techniques in electronic circuits
  • Explore power supply design for analog devices
  • Investigate common issues with DAC power supply connections
USEFUL FOR

Electronics engineers, hobbyists working with DACs, and anyone involved in designing circuits that utilize the DAC813 for signal conversion.

Hello, could someone please verify the proper way to supply power to this particular DAC chip: http://focus.ti.com/lit/ds/symlink/dac813.pdf

Do I need to supply both +15 V and -15 V into +Vcc and -Vcc respectively? Or do I just supply +15 V to +Vcc and have the negative return lead of that supply connect to -Vcc? I don't believe I'm understanding their documentation fully.

Any help or input would be appreciated

Thank you,

Roots

It needs a POSITIVE supply to pin 8 and a NEGATIVE supply to pin 10.

This is mentioned several times.

Pin 5 and pin 16 are grounded.
