TPA0211: Class AB amplifier with BTL,SE outputs

Hi Narendra,

I think Vo = 12pk is my main concern to find a part that fits in here, but I'm trying to understand better the application:

• Are you planning to dynamically change from SE (headphones) to BTL (speaker) when the headphone is plugged in?
• Perhaps using separate amplifiers, using the headphone jack insert as enable/disable control could be an option?

Actually it's not dynamically I want to use a switch to make differential outputs to single ended outputs if available please share it tq I will be happy if you share the part which is having 12 V peak output

Hi Narendra,

Is it possible you can elaborate on a block diagram? Would a 2 chip solution be possible for your application?

Hi yes even 2.chip solution if possible please let me know below is the block diagram.

Let me know if TPA0611 part Pspice library available in Pspice tool directly

Hi Nilendra,

Considering the way you plan to toggle between Differential and Single-Ended output, you may use a differential output OpAmp that can simply load to GND one of the outputs.

Some options you may consider:

• OPA1632
• OPA1637
• LME49724

These devices have TINA and Spice models available on its product folders.

Hi TPA0611 model Is it available in Pspice library 

Hi Narendra,

I could not find any reference of TPA0611, did you mean TPA0211?
As mentioned in one of the other threads, I could not find TPA0211 model in our repositories.

Hi if TPA0211 model is not available how can i test my circuit

Narendra,

There is an evaluation module available for this part you may use: https://www.ti.com/product/TPA0211#design-development
