10 Power Supply Recommendations

The LM26 has excellent power supply noise rejection. Listed below is a variety of signals used to test the LM26 power supply rejection. False triggering of the output was not observed when these signals where coupled into the V+ pin of the LM26.

  • square wave 400 kHz, 1 Vp-p
  • square wave 2 kHz, 200 mVp-p
  • sine wave 100 Hz to 1 MHz, 200 mVp-p

Testing was done while maintaining the temperature of the LM26 one degree centigrade way from the trip point with the output not activated.
