Overview

  • DC Performance:
    Quiescent Current: 400 µA Max
    Bias Current: 10pA Max
    Noise: 2µV p-p typical, 0.1 to 10Hz
  • AC Performance:
    Slew Rate: 1.8V/µs typical
    Unity Gain Bandwidth: 1MHz typical

The AD648 is a matched pair of low-power, precision monolithic operational amplifiers. It offers both low bias current (10pA max, warmed up) and low quiescent current (400µA max) and is fabricated with ion-implanted FET and laser wafer trimming technologies. Input bias current is guaranteed over the AD648's entire common-mode voltage range.

The AD648 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 AD648'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 and high open-loop gain ensures better then 12-bit linearity in high impedance, buffer applications.
