Bill of Materials
This open source hardware project contains no parts.
Steps
26. Insert capacitors
Insert the 0.01uF (marked 103) ceramic capacitor in the holes for capacitor C8. Insert the five 0.1uF (marked 104) ceramic capacitors in the holes for C2, C3, C5, C6, and C7.
27. Solder capacitors
Bend the legs of the capacitors so they don't fall out and solder them in place. I found it helpful to clip each lead after I soldered it so they didn't get in my way.
28. Insert DAC
Insert the MCP4921 integrated circuit in the holes marked for IC2. This is a 12-bit digital-to-analog converter. Make sure the dimple on the chip lines up with the silk screen printed on the circuit board.
29. Solder DAC
Solder the leads of the IC. You don't need to clip these leads since they are already short.
30. Insert and solder op-amp
Insert the TS922IN next in the holes for IC3. This is an op-amp. Make sure that the dimple on the chip lines up with the markings on the circuit board. Solder this IC in place.
