Posted on May 11, 2015 at 02:41The TDA7391 (http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/CD00000162.pdf) has two pins that are named MUTE and SYNC. SYNC is supposed to be connected to ground through a resistor (...
Posted on May 08, 2015 at 23:17Hello, I am designing an Audio Amplifier that is capable of connecting to 4 ohm, 6 ohm and 8 ohm speakers. I need to be able to run at an output of 25W at 25V so I decided to go with the TDA7492P. For reference, I have...
Posted on April 21, 2015 at 17:23Hello,I want to save between 1 and 5 noises or sounds as reference, whenever;Nr1 noise is played (source can be input of speakers) the relay needs to be switched 1 timeNr2 noise is played (source can be input of spea...
Posted on March 09, 2015 at 18:12Hi, Does someone has this IC's datasheet? Or better, can someone help my buy some of those chips? Thank you very much, Alex
Posted on March 19, 2015 at 12:02Is there a replacement for the TDA2003 or can any one recommend a similar audio amplifier that can drive loads down to 1 ohm? #tda2003
Posted on January 15, 2015 at 18:00hi all,i am building an demo application that works right from powering up.Therefore i added an I2C Master to the STEVAL-CCA035V1 and STEVAL-CCA030V1.I can succesfully write the registers of the device and i can al...

Posted on November 24, 2014 at 12:52Hello, I built a system using a ad converter (PCM4202 from TI) and a sta311b DSP. I drive the power fets with the ffx pwm stage of the sta311b. When I measure the phase response of the hole system (without any dsp...
Posted on November 17, 2014 at 16:37Hello, do you have a plot for the phase response of the sta311b dsp ic from DDS or PCM data input to pwm output? Thanks a lot. Best regards EDIT: Same Topic in another Thread: [DEAD LINK /public/STe2ecommunities...
Posted on November 28, 2014 at 09:04Hi, Is there tmeperature drift difference between the two types? Or is there any other difference between the two type,please? Thanks!
