[sdiy] Most common ICs

[Olivier Gillet]

Op-amps:
TL07x (CV, circuits in which another element will add noise/distortion
to the point that the op-amp contribution won't matter much)
OPAx171 (when a TL07x won't cut it because lower offsets are needed
and/or signals will reach the rails)
OPA165x, LME497x0 (when a TL07x won't cut it in terms of noise/distortion)
LM32x (single-supply "analog logic", or when I need just one little
extra amp to drive a LED)
MCP600x (single-supply scaling / summing / filtering of CVs before
they hit the µC's ADCs)

Switching:
DG408/DG409 (or CD405x when +/- 5V supply)

Voltage-controlled elements:
V2164
LM13700 when the non-linearity is wanted

Reference, regulators:
LM4040
LM1117

Conversion:
DAC85xx or DAC86xx for CV generation (well-specified DC behaviour)
WM8731, PCM3060, PCM1780 for audio I/O

MCU:
ATMega328p for low performance
STM32F103CBT6 for higher performance (control, interfacing)
STM32F405RGT6 for audio DSP
