pffb

Hi amigos, I'm sharing a little discovery at a very reasonable price. I found this module particularly interesting, even though it doesn't seem to have a PFFB circuit. The components seem to be of good quality, especially the flat coil inductors. This module reminds me a bit of the 3E AUDIO...

Hi amigos Just to share I found this new dual TPA3255 + PFFB. The price seems very attractive. Makes me think the 3E Audio A7 BTW. I wish Amir could test it. See attached files for details Main spec : PFFB Dual TPA3255 (seems to be a one chip per channel) Trigger Pre-out Upgradable Op Amps...

Hi Amigoes We are preparing to build a multi-channel amp. Wanna know which model is more popular for users? If you are interested, please help us get your vote. Leverage A5(TPA3251),A7(TPA3255) PFFB design with built-in GaN Power supply Pure-Amplifier without volume control, configurable...

This gentleman ‘Guntars Smits’ reads TI PFFB implementation document and describes its too complicated and mostly not really needed unless application demands like running horn tweeters. Is he making any sense?

This is a review and detailed measurements of the O-NOORUS D4 stereo integrated amplifier. It was sent to me by the company and costs US$139 from them direct with the 48V/5A power brick. It is fundamentally a small box TPA3255 design with PFFB to give a flat response into any load, but it has...

Dear FMs, This is "User Impressions, Observations and Owners Thread" for O-Noorus D4 Amplifier (or Stereo Receiver, as has ESS 9023P based DAC as well). While we await if and when D4 get's measured on ASR, this thread hopefully will capture available details, features, internal pics, quick...

Dear FMs, Putting up this thread Aiyima's new A80 DAC + Amplifier - User Impressions, feedback/issues & observations. Product Details: AIYIMA's Portal Quick Summary technical components inside Aiyima A80: - Amplifier: TPA3255D2 with PFFB ckt - DAC used: ESS9038Q2M - Digital volume control...

If you take the different power output options (through internal or external PSUs) off the table, do the current Class D chip amps measure up to a Hypex Ncore? Will a TPA3255+PFFB sound the same top-to-bottom as a NC252MP at 2 watts with a 4-ohm speaker? Or is there still something...

Hi Amigos: It has been for around 2 years after we release TPA3251 and TPA3255 series amplifier DIY kits with post filter feedback design that improve the overall performance of the single chip itself. With many buyers(diyer) enjoyed our diy kits and having so many fun from their own diy...

Hi amigos, I'm coming back to the forefront with a new project. This time I focused on the Sylph Audio FB100 module, based on a TPA3251 and an advanced implementation of the PFFB. Voltage Gain is factory set @ 14dB (5V/V) on this module. So I intended to couple it to my DAC SMSL D6s which has...
