TPA2028D1: spec check

GARETH OU

Part Number: TPA2028D1

Hi

Can I use TPA2028 for both products?

One set of speakers is connected to 2W/4Ω (set Max.<2.5W)

The other group is connected to the speaker 1W/7Ω (set Max.<0.02W)

    Hi Gareth,

    I'm assuming this is TPA2028D1 connected to only one of these speakers at a time, correct?
    This device should be good for this application. You can see from data sheet Figures 15 (8Ω) and 16 (Ω) that THD+N is still low at 1W and 2W respectively. For 7Ω you can expect slightly higher power for a given THD+N level compared to 8Ω.

    Best regards,
