Precision, Low Power Bifet Op Amp

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 A max) and is fabricated with ion-implanted FET and laser wafer trimming technologies. Input bias current is guaranteed over the AD548s 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 V/C. The C grade reduces input offset voltage to less than 0.25 mV and offset voltage drift to less than 2 V/C. This level of dc precision is achieved utilizing Analogs laser wafer drift trimming process. The combination of low quiescent cur- rent and low offset voltage drift minimizes changes in input off- set voltage due to self-heating effects. Four additional grades are offered over the commercial, industrial and military temperature ranges. The AD548 is recommended for any dual supply op amp appli- cation requiring low power and excellent dc and ac perfor- mance. In applications such as battery-powered, precision instrument front ends and CMOS DAC Buffers the AD548s excellent combination of low input offset voltage and drift, low bias current and low 1/f noise reduces output errors. High com- mon-mode rejection (86 dB, min on the C grade) and high open-loop gain ensures better than 12-bit linearity in high im- pedance, Buffer applications. The AD548 is pinned out in a standard op amp configuration and is available in six performance grades. The AD548J and AD548K are rated over the commercial temperature range of 0C to +70C. The AD548A, AD548B and AD548C are rated over the industrial temperature range of 40C to +85C. The AD548S is rated over the military temperature range of 55C to +125C and is available processed to MIL-STD-883B, Rev. C. The AD548 is available in an 8-pin plastic mini-DIP, cerdip, TO-99 metal CAN surface mount (SOIC), or in chip form. By Analog Devices, Inc.
