TPA6211A1: Vdd Cap Selection

Part Number: TPA6211A1

Hello,

Quick question on the VDD cap selection. Is a 100uF/10V Tantal cap with 600mOhm ESR low enough ESR or any concerns?

100uF rather than 10uF selected for historical reasons in the audio amp design.

Regards,

Viktor

    Hi Viktor,

    The suggested capacitor may be OK, I would still suggest to test the performance in terms of power up and power down. ESR would affect the supply ramping. What are you planning to use for Bypass cap?

    Best regards,
