AD8506ARMZ-R2

20レA最大，轨至轨I / O，零输入交越失真放大器 20 レA Maximum, Rail-to-Rail I/O, Zero Input Crossover Distortion Amplifiers

GENERAL DESCRIPTION

The AD8506/AD8508 are dual and quad micropower amplifiers featuring rail-to-rail input and output swings while operating from a 1.8 V to 5 V single or from ±0.9 V to ±2.5 V dual power supply. Using a novel circuit technology, these low cost amplifiers offer zero crossover distortion excellent PSRR and CMRR perform ance and very low bias current, while operating with a supply current of less than 20 μA per amplifier. This amplifier family offers the lowest noise in its power class.
