Logarithmic and antilogarithmic amplifier IC featuring a 1.4MHz gain bandwidth product and 45kHz -3dB bandwidth. This dual-channel, single-circuit amplifier operates from a 4.5V to 18V dual supply or 36V single supply, offering 100dB common mode rejection and 106.02dB power supply rejection. With a low 5pA input bias current and 1.5mV input offset voltage, it is housed in a 14-pin SOIC package and is RoHS compliant.
