TAS5624A Gain Variation vs Power Supply Voltage

Kato-san,

What is the specific conditions such as load, Po and supply range?

reg,

Paul.

Hi Paul-san,

Thank you for your quick response.
The conditions are shown as below.

Pout : 80W ~ 120W(non-clipping output voltage)
Rload : 4Ω
PVDD_X : 28V ~ 36V
Output Configuration : BTL

Could you please tell us "the gain variation vs the power supply voltage" in above conditions?
In addition, we would like to know the difference between the devices(e.g. TAS5352A, TAS5261/2) of the open-loop system.

Best Reagards,

Hi Paul-san,

We evaluated TAS5624A evm which is mounted TAS5538 as the pwm modulator in your local office since we did not have it.
Then, that result for the load impedance of 6ohm and the output power of 61W is shown as below, the result of "PVDD=36V" is plotted on the basis of the result of "PVDD=28V".
That issue has been closed since we understood that the gain variation is very small.

Hi Paul-san,

Thank you for confirming.
We will contact you if we have any questions.

Best Regards,
