DAC I/V stage - Xmas Project #4

[Ray P]

It was nice and quiet this morning so I tucked myself away and set about soldering up some I/V stages that I got via a DIY Audio group buy - it's a 'Simple Discrete Current-Mirror IV Converter, à la AD844'. The group buy organiser proved the PCBs and sets of matched transistors. Information on the circuit is here

There was a time when I would avoid smd soldering like the plague but I'm getting the hang of it mow - these boards are tiny (as you can see by the twenty pence piece) and the resistors are 0603 size. The job is not perfect with a few squiffy parts but overall I'm pleased with what I managed to do with hand soldering. These will go into an AD1862 (or AD1865) R2R DAC that I'm collecting parts for.

Very impressive soldering
