5. Now warm up your soldering iron and solder the two 2.0K ohm resistors from pins 12 and
13 to the 5V solder pad shown in Figure 7.28.
6. Now prepare the two wires that you will be soldering to the audio jacks on the back of the
2600 case. Cut two lengths of 18-gauge wire, each about a foot long.These wires will run
from the TIA chip to the back of the case. Solder a 0.1uF capacitor to each of these cables.
You might want to cut a 1-inch or so length of 1/32-inch heat-shrink tubing and slide it
over each of these cables—these will help shield the connections you make to the TIA chip.
If you don’t have heat-shrink tubing, you can also use electrical ...
