Application Note of the day

Arduino is fed by a single supply (actually +5 V DC) from which many simple interface circuits can be powered. While this is just fine for digital interfaces, it may be tricky when designing analog circuitry. Here is a very nicely written Application Note from TI, describing “A Single-Supply Op-Amp Circuit Collection”. This Application Note (SLOA058– November 2000) comes with schematics, formulas and explanations. A must read. Follow this thread....
