TPA3255: Output phase delay

Umberto Frangi

Part Number: TPA3255

Hi,

if you put a low frequency sinewave into two devices,configured as PBTL and with same load,same external components, what is the max output phase delay difference between them?

Thanks

Hi Umberto,
We are looking into this and will get back to you later.

Hi Umberto,

When using two devices in the same system, we recommend synchronizing the devices with the use of the oscillator pins. This allows one device to be the master and the other to be the slave. This will have a guaranteed phase delay between the two amplifiers. Please take a look a the 10.2.1.2.4 section of the TPA3255 data sheet and the Multi-Device Configuration for TPA32xx Amplifiers application note.
