Hello; I have the electronic circut card including ST microelectronics IC component. On the top of component, 256D is written. SOIC8 package I couldnt find any tecnical information on the internet. According to electronic circuit, it seems an OPAMP n...
MC33078:what's the meaning about MZ,GZ,EZ markcode on the top of IC?if it means different places of production? We find that the MC33078 with different markcode influences the tone colour we listen.The MC33078 is used in our KTV PROCESSOR
Hello, I have simulated the spice model of LM2904 in LTSPICE for the input voltages as shown in figure , as per the theoretical calculation output voltage will saturate to supply voltage VCC=12 V , but from simulation results output voltage getting...
If i want to run TDA7498e as a monoblock, do i then need the capacitors on pin 32 / 33..?Both pins are tiet to ground in mono.
Hi, I have an active subwoofer with a burned chip on it. Unfortunately the model number is unreadable in the last number/s. The reading says TDA729* and under it CZ041936. Is there a way to get the correct model? I tried to contact the manufacturer o...
Basically we are thinking to use sensor tile as a voice recognition module and for that we need some info regarding module train process how it will easy for user to train any customize voice ?And this voice recognition module able to distinguish two...
The ic is damaged, came from Epson Proyector S41+.It is an integrated audio circuit, the integrated circuit is heated and there is no audio coming from it, it is a surface welding circuit. I need the datasheet or know the audio input and output pins ...
Hey guys,I am using a STM32 F411E DISCO board and downloaded ST FP AUD_SMARTMIC1 library to learn audio feedback suppression caused by a mic and a PA ampliflier nearby. In the library C files given in the projects folder of FP AUD_SMARTMIC1, they are...
