I am looking for a part for my Mercedes Audio system, part # 7569B as shown in the attached image

Can't set SPIRIT1 status to lock Tx or Rx

I have been using STEVAL-IKR002V4D (a daughterboard with SPIRIT1 868 Mhz transceiver) to transmit data. I have it hooked with Raspberry Pi. I have followed the driver library example provided in the design kit software. However, I can't initialize th...

LM2901 : Common mode input voltage range.

What will happen with output when input signal is out of "Common mode input voltage range"?Ex.) Vcc=5V (Vicm= 0 to 3.5V) ---> Input IN-=0V, IN+=4V signals Then, Output go to 5V(saturated)?

How to set STA311 for 2.1

Hi, How to set STA311 for 2.1 by APWorkbench? for example, ch1 and ch2 mix to ch6 output.

I have been testing with TDA7294 and need to switch to TDA7293. My test board works fine with the TDA7294 but when I put in a TDA7293 with no load and apply power to the device it draws massive amount of current. Can you tell me what i am doing wrong.

I need to run the TDA7293 because i wont to run 50 volts rails. I am so confused , i thought the parts were pin compatible. I have read the data sheet a few times and don't quite understand what is wrong. I am basically using the schematic of the...

What is the range of frequency that 1N5711 diode can operate at my element? OR What is the range of Reverse Recovery Time of 1N5711 diode at my element? (Trr) OR What is the cutoff frequency at my element?

Hello. My name is Dae Hun Hwang from Korea.​I am making Lectenna. (LED + Rectify + Antenna)​I attached my circuit and picture.​Length of my element is about 6cm.​I used normal LED and 1N5711.​I am experimenting at 2.4GHz.​Thank you.​

What is the range of frequency that 1N5711 schottky diode can operate? (Right Switching Action) (ex. 100MHz ~ 10GHz) OR What is the range of Reverse Recovery Time of 1N5711 diode?
