Other Parts Discussed in Thread: TPA6203A1 Hi All,
In a portable, battery powered design, we're using the TPA6203A1 audio amplifier to drive an 8 ohm speaker. It's set up using the application schematic shown in figure 30 of the data sheet. I've attached…
Other Parts Discussed in Thread: TPA6203A1 Hi Team,
Please help advise compatible part of TPA6203A, and it needs to be pin to pin compatible.
The PSRR and CMRR needs to be better than TPA6203A.
Lower noise is the top priority.

Hi Diego,
I had download AIC1110 EVM layout file…but its only has three pages inside and it is not enough information for help the layout.
Can you help provide the layout guide such as TPA6203A1 see attachment. Thanks

Hi
I've noticed that if I turn on the amp shortly after I turn it off I hear a pop sound.
my investigation showed that the bypass capcitor takes a long time to discharge. when I assert the SHDNn pin high, it discharges it very rapidly (a few uS…
Hi, John,
Sorry for the delay in getting back to you.
What is your source doing when you're shutting down the TPA6203A1? Is it also being shutdown? Is the pop being generated by the previous stage, and being fed to our amplifier?
I noticed your…
Other Parts Discussed in Thread: TPA6203A1 Hi,
Can someone explain how the DC bias is set on the inputs (In + and In -) of the TPA6203A1 on the EVM? It seems like they will drift to an arbitrary DC level unless you add a pull up or pull down.
Hello Paul,
The pop noise is caused by an unbalanced input in a Single-ended input configuration, so you could use a differential input configuration to avoid this issue. If you can't change the input configuration, so you verify that the tolerance…
Hi Eli
Unfortunately, We don't have an improved version of this device. But you can take a look to the following devices: TPA6203A1 and TPA6205A1, they have similar pins.
Please let me know your opinion.

Hi Ito-san,
Q1) The pop noise level depends on the system's design. Q2) First of all, I can't watch in the schematic what kind of input you are using. The pop noise is produced by an unbalanced input if you are using a single-ended input It is recommended…
Hi Daniel,
The schematic and layout seem to be right.
You can have a look at the following devices: TPA0213 and TPA0211, they are mono class-AB audio amplifiers with stereo headphones and they are able to deliver higher output power than LM4864. I…
