TAS3308 programmable PWM Modulation Limit

Other Parts Discussed in Thread: TAS5631, TAS3308

I use the TAS5631 with a TAS3308 Audio Processor, which Modulation Limit is 69.1% default (programmable) and will set it to 97.7% (limit of the TAS5631).

Section “14.12 PWM Channel Delay, Modulation limit and Offset (0x1A)” describes the bits to be set are BS0..BS2 but I can’t find a table which describes which setting is which limit…

    Hi, Mathias,

    I believe TAS3308 is going to be set to NRND (Not Recommended for New Designs) very soon. Basically, once we set a part to NRND, it is still fully available for ordering, but we don't dedicate resources to supporting customer questions as much.

    So, it looks like your best best bet is trial and error... Sorry, I couldn't find this data in any of the information I have access to.
