The AD548 is a low power, high precision monolithic operational amplifier that offers both low bias current (10 pA max, warmed up) and low quiescent current (200 µA max). It is fabricated with ion-implanted FET and laser wafer trimming technologies. Input bias current is guaranteed over the AD548's entire common-mode voltage range. The economical J grade has a maximum guaranteed input offset voltage of less than 2 mV and an input offset voltage drift of less than 20 µV/°C. This level of dc precision is achieved utilizing Analog's laser wafer drift trimming process. The combination of low quiescent current and low offset voltage drift minimizes changes in input offset voltage due to self-heating effects. The AD548 is recommended for any dual supply op amp application requiring low power and excellent dc and ac performance. In applications such as battery-powered, precision instrument front ends and CMOS, the AD548 is ideal.
