Part Number: TPA3251TPA3251D2 cannot reduce output noise in SE 2.1 mode. Please listen to the audio file recorded in the attachment.
PIN15 C_ We made a lot of adjustments to START, but it was useless.
Is there any way to reduce the noise of this on-off…
Part Number: TPA3251 There is a pop noise during powering up and down, the waveform as below:
Output SE configuration.
Noise happens at all output channels.
Increase C-start capacitor with 0.82uF in parallel, there is…
Part Number: TPA3251 Hello, I have some valuable information regarding the TPA3251 chip. I am currently working on designing a speaker system, and I would like to inquire about the technical feasibility of my project before proceeding with an order. I…
Part Number: TPA3251TPA3251 with AP software test 4R load work normally, but when adding music signal impedance 4R horn speaker, BTL protection problems, SE mode work is normally. The voltage goes from 36V to 27V the problem is the same.
Part Number: TPA3251 Other Parts Discussed in Thread: DRA788 , TAS3251 Hi,
Good Day. I have a customer who is working with TPA3251 and DRA788. Please see below his query for your reference. Thank you very much.
1. I'm going to make an audio amplifier that…
Part Number: TPA3251TPA3251 plugging a driver into a running unit causes loud pop. Could be bad user experience.
It happened on SE channel, the output is charged to 1/2 PVDD after startup. Whether it can be improved by reducing C_START capacitance.
Part Number: TPA3251 Hello
I have a similar problem with a new prototype with TPA3251 (the reset remains low level, fault and clip high level). The reset is piloted by a TCM 809 and host controler.
Have you solved your problem? may be I can solve mine…
