Part Number: TPA3251D2EVM Hello,
I am looking for the PCB CAD file. Is this Eagle or Altium file?
Please kindly point me to the URL.
Thank you.

Part Number: TPA3251D2EVM We have designed a driver amp for a special purpose that is similar to a sub-woofer amp function. DC to 250hz response. The TPA3251D2 looked better than our previous attempt so we have designed around it. The one problem the…
I'm seeing Vin/2 at the PWM A and B output relative to Gnd so I think the whole amp output has a DC offset of half the Input voltage.This would make sense as I can only put half the signal I should be able to put in at the RCA before clipping which when…
Part Number: TPA3251D2EVM Hi,
Set TPA3251D2EVM 2.1 mode, Load is 8ohm, test result is as below.
input power, 34.7V*2.9A=100.63W.
output power, 2*(10V*10V/8)+21.5V*21.5/8=87.78W
η= 87.78/100.63=82.26% .
Why is the eficiency so low?
Part Number: TPA3251D2EVM Can I use this TPA3251D2EVM board in the ultrasonic frequency range of 60 ~ 80kHz? Since fpwm is 600 kHz, it seems that it can be used only by replacing the LC filter. am i right?
thank you
Hi Steve.
Rev02 has not yet been realized, so I do not know the values of the Fault and Clip pins. When I measured them on the first version, they were active which of course is a problem.
I had noise on the output, and nothing that really made sense…
Part Number: TPA3251D2EVM After completing a 2x80W power amp design, I'm having difficulty with the way TPA 3251 sounds. This is after numerous listening tests and comparisons with a 2x100W power amplifier (with good review by magazine), a 2x50W analog…
