Description

  • Typical Application Circuit for AD8508ACBZ-REEL7 Pulse Oximeter Red and Infrared Current Sources as a Buffer to the Voltage Reference Device. The AD8508 is a quad Micro-power amplifier featuring rail-to-rail input/output swings while operating from a single 1.8V to 5V power supply or from dual ¦0.9V to ¦2.5V power supplies. Using a new circuit technology, these amplifiers offer zero input crossover distortion (excellent PSRR and CMRR performance) and low bias current while operating with a supply current of less than 20 uA per amplifier
