yes the input voltage at U2 varies from 0 to +11.4V....
then what should i do... -
when the U2 will measure zero... what should i check it is not working...
-
i have made some mistakes in the pcb and i have corrected it now the led is not glowing and voltage at the current is 1.8, the output of U1 +11.4...
but even i am not able to vary the voltage... :(
at c1 it is 28.6V
hi redwire can u post the pcb u made??? -
hi
here is an datasheet of an ic from ti, can u help me to put a volume controller to this circuit and what is meant by 4step gain control, multiple class d devices, shut down and mute control.... ???
what should be the input voltage and current?

the wiper at one end of the pot measures 4.7V and at other end -0.6V input voltage of U3....next hat should i do..
-
my psu seems to be not working there is no voltage variation and i have used tle2141 opamps....what should i do.... ??? :( the led is glowing without any load....
i have posted the circuit diagram and the pcb made by me...
-
hi
what are the things to be checked before connecting the circuit to load...
and i have used only 24volts 3amps transformer what will be the maximum power delivered to the output ??? -
so can i use an 20W amplifier to an 60W 4 ohms speaker.....
-
hi
i have a doubt that an 20W amplifier can be used to 60W speakers ??? if not post a circuit for 2x60W audio amplifier.... -
thanks for the information provided i am update the complete circuit once i have build it...
-
hi
i have drawn the fm transmitter circuit with the preamplifier kindly provide me the operation of this circuit ???
-
hi
can u post me anyone circuit here pls ??? -
hi
can u modify this circuit with an electret mic and all the correction to work well because
i am looking for a smaller size transmitter ???
the previous circuit u gave works fine too...but little big one :( -
hi
how to add an condenser mic to this circuit is this circuit transmit well ???
ur opinion pls...
-
hi
any circuit that will transmit voice for 100meters range using fm but the transmitter must be small enough... -
hi
using the fm transmitter module how to transmit and receiver voice..
link for that fm module

pls help me to construct a circuit.... ??? -
hi
how test a condenser mic ??? -
hi
i am talking about the center of the ift is red in colour -
hi
how to find the value of the IFT coil???
i c a red color plastic or an grey color how to identify it ??? -
is there any other substitute to overcome this ??? -
hi
i need a circuit to lit 50 leds in ac voltage 230v,50Hz... -
hi
ok chill hero999...
why i am asking is that i have those components with me so that is why i was asking about that circuit....kindly help me out to do this circuit....
i cant get LM2931A...is there any substitute ??? -
hi
the circuit diagram pls check the working of this circuit...
-
hi
i am not able to upload pictures to the threads..
the info. displayed is
The attachments upload directory is not writable
what to do ???

the output of U2 reads 28.5V when in input of U2 above 0.5V and output U2 reads zero at input is zero
