TPA0253 replacement part

Other Parts Discussed in Thread: TPA0253, TPA0213, TPA0233

Team,

My customer is looking for a replacement part of TPA0253 as following requirements.
- Output gain: 24dB (current: 18dB with TPA0253)
- Output: 0.3W typical, 1W max.
- Class A/B or D
- L/R input, Mono output
- Lower noise than TPS0253
- Nice to have a functionality of output muting by input signal level.

I think TPA0213 could be one candidate. Could you please let me know if there are any other good parts which are suitable for these requirements?

Regards,
Nobuhiko Wasa

Hi Nobuhiko

As you mentioned the TPA0213 fits into your application. But you could also have a look to the TPA0233.

Jose,

Comparing noise performance between TPA0253 and TPS0213, it looks almost the same because characteristics below are mentioned in different RL. Is there any advantage on TPA0213 in terms of noise performance?

Nobuhiko,

It seems that they have the similar noise performance. They also have the same PSRR, this parameter indicates the amount of noise from a power supply that a device can reject.

Nobuhiko,

Sorry for the delay. Unfortunately, there aren't other similar devices. The other ones have worse noise performance.
