Other Parts Discussed in Thread: OPA4134, OPA2134,
We have used the TPS 65133 in our design which providessplit rail power to 3x OPA4134 opamps and 1x OPA2134 audio amplifiers.
The TPS 65133 is capable of powering 3 of the 4 opamps (total of 60mA on the -5v rail with 3 opamps) but when the 4th opamp is connected, the +5V stays on but the -5V goes to 0.6V.
We haved used x7r capacitors and wire wound inductors with correct component values, however couldnt source the recommended components.
Any assistance would be appreciated.
