Hi Raphael,
2question,
(1)Base on tas2564 datasheet indicate 7W VBAT=3.8V@8ohms THD is 0.1%, what test condition, is use EVM?
(2)Please help check attachment TAS2564 .hex file is there a problem that needs to be modified. TAS2564 config.h
Hi Ivan,
Would you help provide PPC-3 GUI Boost condition for 7W? as now I just measured Po is 2W.
(1)Audio is USB in, and 1KHz// Sinwave// 0dB
(2)Speaker:8phm
(3)TAS2564 EVB Vin: 3.5V
(4)PPC3 EVB Vin: 5V
Hi Shenghao ,
I tried to include lpaa-android-drivers/tasdriver-linux-driver into my Yocto project as an external module but it fails at compilation : error: 'FW_ACTION_UEVENT' undeclared

we have a temporary provision of the problem. In out device, the amplifier works with NRF52 microcontroller with embedded bluetooth. The sound distortion disappears if bluetooth advertising is switched off. Apparently there is some interference between…
Hi MJ,
Some options we could think of are TAS5721, TAS2770 or TAS2564. TAS2x devices are mono, TAS2564 has an integrated boost in case you need to supply the amplifier from some lower battery voltage.
EQ would be the main concern as some of our devices…
Hi Antonio,
TAS2770 and TAS2564 are what we all "external boost supply" devices, as opposed to other solutions like TAS2563 where the boost is integrated in the device.
TAS2564 is newer and thus have some new features like Y-Bridge, which is…
