  • use 1% resistors, no need to use expensive 0.1% ones
  • add SERVMOD pulldown control (MOSFET at R7)
  • the power stage needs to have common mode voltage at 3V. DAC generates 0-2.048V so common voltage is 1V. It is then doubled by U1B, but additional offset is needed. Look how it's done in Magneto
