Part Number: TPA2037D1 In our design, we have both 3.3V (for MCU/digital) and 2.8V (for audio/analog). The TPA2037D1 is on the 2.8V LDO but we accidentally tied its "EN" pin to a 3.3V GPIO signal with no voltage divider. That GPIO is driven by another…
Hello Luis-san,
No, my customer is trying to pick up parts.
Does TPA2034D1 or TPA2037D1 you mentioned have pop noise suppression circuit inside?

Hi, Jerry,
The input resistance may vary depending of the test conditions. As shown in the electrical characteristics, the input resistance depends of some parameters:
For the TPA2037D1:

Hi, Jerry,
Yes, the TPA2037D1 requires of this common-mode or bias voltage to work correctly. If the input capacitors are removed, the output performance may be affected as shown in your second picture.
If your system cannot generate the bias voltage…
Hi Scott,
You can have a look the following devices: TPA2011D1, TPA2037D1, TPA2033D1 and TPA2010D1, they can fit in your application.

Hi Jay
You could take a look to the following devices: TPA2011D1, TPA2037D1 and TPA2038D1, they have high efficiency.
On the other hand, the TPA2028D1 has Automatic Gain Control (AGC), It can be configured for a specific audio source like Voice, Rock…
Hi Jonathan:
The TPA2037D1 and TPA2039D1 are both good choices, too.
All three amps are used in current portable devices and should be available for a long time.
The TPA2038D1 is as stable as the other two choices due it its internal layout being…
