How to Create a Battery-Operated +/- 15 Volt Power Supply for Op Amps?

Click For Summary
SUMMARY

This discussion focuses on creating a battery-operated +/- 15 volt power supply specifically for operational amplifiers (op amps). A recommended solution involves using a DC-DC converter, such as the MT2-1215WI model from Digi-Key, which efficiently provides the necessary voltage with a 100mA output. The use of a voltage regulator is emphasized to ensure proper voltage distribution from the main power source. The datasheet for the converter provides essential connection details and pin configurations.

PREREQUISITES
  • Understanding of DC-DC converter functionality
  • Familiarity with voltage regulation techniques
  • Basic knowledge of op amp power requirements
  • Ability to read and interpret datasheets
NEXT STEPS
  • Research the specifications and applications of the MT2-1215WI DC-DC converter
  • Learn about different voltage regulator types and their uses
  • Explore circuit design for battery-operated power supplies
  • Investigate best practices for connecting op amps in power circuits
USEFUL FOR

Electronics hobbyists, circuit designers, and engineers working on battery-powered applications requiring stable voltage for operational amplifiers.

I need a battery operated +/- 15 volt power supply. I'm going to use it to run a couple op amps. Any help with a circuit? Thanks

You can use a voltage regulator to distribute the appropriate voltage using a power distribution circuit, from your main voltage source.
 
If you only need 100ma output something like this would do:

dc-dc works best.

it cost a little but will save you the time to keep your project moving. Datasheet shows how you can connect things and output and which pins
