Dual precision logarithmic and log ratio amplifier featuring a 1.4MHz gain bandwidth product and 45kHz -3dB bandwidth. This integrated circuit offers a 1.5mV input offset voltage and 5pA input bias current, with a 100dB common mode rejection ratio. Operating from a 4.5V to 18V dual supply, it provides a 0.5V/µs slew rate and 1.25mA operating supply current. Packaged in a 16-SOIC, this RoHS compliant component is suitable for operation between -40°C and 85°C.
