QAKAMP contains four bridge amplifiers with 2+ pole LP filters and differential output drivers, a high current precision voltage reference, power supply conditioning. The front end uses instrumentation amplifier with 80dB CMR extending to 100KHz.
Rev A
- LM358 and OP27 opamp power wired backwards - corrected in Rev B schematic
- V- LED wired backwards in SCH, corrected in Rev B sch
SN1 : assembly notes
- Vref built with TL1431, Ra=2.49, Rb=4.7k -> Vref = 7.2v
