Part Number: TPA3255 Tool/software: Hi teams,
I previously mentioned an issue related to TPA3255 overheating https://e2e.ti.com/support/audio-group/audio/f/audio-forum/1416433/tpa3255-tpa3255-19pin-and-21-pin-error
I don't care about the switching frequency…
Part Number: TPA3255 Tool/software: Hello,
I am working on a design using the TPA3255 class D audio amp IC. My design is based on the TPA3255EVM configured as 4 SE channels. My design is only using channel A and B, would I still need he large 4700uf…
Part Number: TPA3255 Tool/software: Hi Team
I need below clarification on TPA3255 EVM Board and ATS-Quats Heatsink assembly
1. How is the assembly of TPA3255 & EVM Board heatsink is assembled , Is there we have any Airgap ? or its face to face connection…
Hi Tien Nguyen,
regarding the current sensing ,you can refer to the datasheet 9.4.1.1:
"9.4.1.1 Overload and Short Circuit Current Protection"
"TPA3255 has fast reacting current sensors with a programmable trip threshold (OC threshold) on all…
Part Number: TPA3255 Tool/software: Dear TI engineers
We found a clipping alarm during testing regarding the design of TPA3255. Both pins 19.21 are reporting an alarm.
Currently, my settings are 3-pin and 4-pin grounded, and 9-pin and 10 pin open 5,…
Part Number: TPA3255 Tool/software: Hi. We are using the TPA3255 on a different application. We made a 3 phases power supply (3 channels for current and 3 channels for voltage). Basically we synthesises a sinusoidal voltage on 50Hz or 60Hz and apply…
Part Number: TPA3255 Tool/software: I've seen other folks discuss using TPA3255 to provide variable controllable current to non-audio loads on the forums previously.
My question is not specific to TPA3255, but any of the TI multichannel integrated…
Part Number: TPA3255 Other Parts Discussed in Thread: LM2904 Tool/software: Hello
i have built this circuit for the speaker driver diagnostic (Class-D Amplifier External Load Diagnostics - SLVA824)
the "SHORTED LOAD" give 111 instead of 110 as stated…
Part Number: TPA3255 Tool/software: Hi,
I have a customer who is using the TPA3255 in a stereo BTL application, however they are seeing significant roll off at 20Hz and 20kHz (around 3.5 dB). What is the expected frequency response of this device given…
