Part Number: TPA3136D2
Other Parts Discussed in Thread: TPA3111D1

Hi Team,

One of my customer is using TPA3136D2 class D power amplifier for one of my testing. It’s a dual channel power amp & have a common shutdown pin.

They wanted an IC which have separate shutdown/mute control for each of the two channel with same specs (output power, THD, SNR). Please let us know if anything available for this.

Regards,

Praveen GD

    Hi Praveen,
    Unfortunately this is not available by SDZ pin on TPA3136D2 - the output on the two channel are turned on or off at the same time.
    One solution is to use two mono output amp(e.g. TPA3111D1) in the app, one device for one channel. The two channels can be controlled seperately by the SDZ pin on the two device.
    Best regards,
