MERUS™ audio amp HAT ZW: configuration - OlafM - 03-25-2020 Hi all, There is new intresting Amp released: Infineon KIT_40W_AMP_HAT-ZW Specs as on website:
1) As it is stated that the driver is supported within Raspbian, by adding dtoverlay=merus-amp in config.txt. Shoul I install Rasbian and than start to install MOODE? 2) Install MOODE and try various DACs? 3) Any other methods? The application note with respect to the SW is at: SW application note Many thanks for your advise, Thanks, Olaf RE: MERUS™ audio amp HAT ZW: configuration - Tim Curtis - 03-25-2020 I asked about it a while back but never got a response from Infineon. https://github.com/Infineon/merus-audio-amp-hat-zw/issues/1 I could probably integrate it into upcoming r650 but we would need to work closely to get the ALSA options defined and tested. -Tim RE: MERUS™ audio amp HAT ZW: configuration - OlafM - 03-26-2020 (03-25-2020, 06:59 PM)Tim Curtis Wrote: I asked about it a while back but never got a response from Infineon. RE: MERUS™ audio amp HAT ZW: configuration - OlafM - 03-26-2020 Hi Tim, Ok, I will try to ask Infineon to provide information. Thanks, Olaf RE: MERUS™ audio amp HAT ZW: configuration - Tim Curtis - 03-26-2020 Whats the point of your post that just repeats my reply. It's looking spammy to me and I've got no tolerance for spammers in our nice Forum. Please explain. RE: MERUS™ audio amp HAT ZW: configuration - Tim Curtis - 03-26-2020 Ok nvm :-) You are getting a board so why involve the vendor? They haven't bothered to respond to me and since your are interested in integrating it we should just work it out. -Tim RE: MERUS™ audio amp HAT ZW: configuration - DRONE7 - 03-26-2020 Looks like there is info for this... https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=2ahUKEwj_1vm6qbfoAhVkyzgGHf3KAiUQFjABegQIARAB&url=https%3A%2F%2Fwww.infineon.com%2Fdgdl%2FInfineon-KIT_40W_AMP_HAT_ZW-UserManual-v01_00-EN.pdf%3FfileId%3D5546d4626eab8fbf016eef8084096be6&usg=AOvVaw2YK1BPRvMrcOhw8O6EOktg https://github.com/Infineon/merus-audio-amp-hat-zw/blob/master/merus_linux_audio_driver/README.md Code: Name: merus-amp RE: MERUS™ audio amp HAT ZW: configuration - CallMeMike - 03-26-2020 (03-25-2020, 03:34 PM)OlafM Wrote: Hi all, ££32.28 plus delivery from Digikey UK *WARNING* Here's a clever marketing ploy from INFINEON... 40W instantaneous peak output power with the Raspberry Pi official 5V/2.5A supply. This is a perfectly technical way (amongst others) for measuring an amplifier's output power and BUT it does not equates to 40W RMS output power from your HiFi amplifier in the lounge!! It is probably delivering just 3-4W RMS power and dissipating an amount of heat which may not be good for your RPi in the long run... RE: MERUS™ audio amp HAT ZW: configuration - jonners - 03-26-2020 Indeed. 40W from a 5v/2.5A supply that also feeds the RPi? That's just ridiculous. RE: MERUS™ audio amp HAT ZW: configuration - OlafM - 03-26-2020 Hi Tim, Just hit the reply button to quickly, sorry for that. In the next days, I will test the Amp with Raspbian. If it it sounds ok for its application (table desk audio), I will come back to you. And we can see how we move forward. From technology point of view, there is a story behind the 40 W peak from a 5V 2.5 A power supply see Application note. and Technology Regards, Olaf |
