Description
The TLN861 Dunsel is a utility module that generates several commonly used signals from an input voltage. When patching my synth, I frequently require unity gain inverters, adders, subtractors, half/full wave recitifiers, and level shifters. While it's possible to generate these signals using MOTM830, Oakley WaveFolder, or Oakley Multimix modules, that's not often the best use of those resources. Enter Captain Dunsel to the rescue.
The Dunsel features two channels (A & B) with the following independant outputs:
 INV A/B: unity gain inversion of input.
 NEG A/B: negative portion of input.
 POS A/B: positive portion of input (half wave rectification).
 FWR A/B: full wave rectified version of input.
 A/B  5: level shifted version of input (5V level shift).
 A/B + 5: level shifted version of input (+5V level shift).
The Dunsel also has the following combined outputs:
 A + B: sum of A and B inputs.
 A  B: difference of A and B inputs.
The TLN861 Dunsel can be built using MUUB daughterboards. The first version I built (Rev 1) used four MUUB4 boards and three MUUB2 boards stacked two or three boards high. That version was a bit cumbersome to put together. I then realized I could simplify things considerably by using two MUUB3 boards and one MUUB2 board (Rev 2).
Contact me if you wish to purchase PCBs.
Total current draw for TLN861 is 38 mA @+15V and 38 mA @15V.
