I am practicing with TLC548 analog to digital converter. First I wanted to simulate in proteus. But it doesn't work. I take sine wave as analog in, Ref+=5V,Ref-=-5V. internal clock 4MHz, CS= ground. No output found. What's wrong ?

Your guess is as good as mine without a schematic of your circuit. :wink:

Pardon me. The circuit is given here: tlc548.PNG
 

As you can easily see in the datasheet, both CS and CLK must be stimulated to get an output from the device.

I did this. If I got pulse in CS there is no o/p. otherwise all time SDO pin shows 0 level. I have used clk 2.048MHz according to data sheet. Still it doesn't work. How can I ensure data conversion is possible using TLC548. My schematic is here:tlc548(1).PNG
