The AD548 is a low power, precision monolithic operational amplifier. It offers both low bias current (10 pA max, warmed up) and low quiescent current (200 μA max) and 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 DAC buffers, the AD548’s excellent combination of low input offset voltage and drift, low bias current, and low 1/f noise reduces output errors. High common-mode rejection (82 dB, min on the “B” grade) and high open-loop gain ensures better than 12-bit linearity in high impedance, buffer applications.The AD548 is pinned out in a standard op amp configuration and is available in three performance grades. The AD548J and AD548K are rated over the commercial temperature range of 0°C to 70°C. The AD548B is rated over the industrial temperature range of –40°C to +85°C.The AD548 is available in an 8-lead plastic mini-DIP and surface-mount (SOIC) packages.PRODUCT HIGHLIGHTS A combination of low supply current, excellent dc and ac performance and low drift makes the AD548 the ideal op amp for high performance, low power applications.
