Digitally Controlled Negative Voltage Supply
Despite the popularity of single-supply ICs, a negative control voltage is still required by some applications. Modern, inverted R-2R ladder DAC and op amp is the solution for this purpose. This approach offers lower supply voltages, higher speed, and smaller packages when compared with older DACs containing standard R-2R ladders. An output swing from 0V to 2.5V is produced by […]
