Precision logarithmic and log ratio amplifier featuring an on-chip 2.5V voltage reference. This integrated circuit offers a 1.4MHz gain bandwidth product and a 45kHz -3dB bandwidth. With a low input bias current of 5pA and a 1.5mV input offset voltage, it operates from a 4.5V to 18V dual supply. The amplifier boasts a 100dB common mode rejection ratio and 106.02dB power supply rejection ratio, packaged in a 14-SOIC for tape and reel distribution.
