The AD8505/AD8506/AD8508 are single, dual, and quad micro- power amplifiers featuring rail-to-rail input/output swings while operating from a single 1.8 V to 5 V power supply or from dual ±0.9 V to ±2.5 V power supplies. Using a new circuit technology, these amplifiers offer zero input cross-over distortion, low noise (45 nV/√Hz at 1 kHz), very low input bias current (1 pA typical), and up to 100 dB of PSRR and 105 dB of CMRR over the entire operating range.
