AD8307 Logarithmic Amplifier

ADI’s AD8307 is a logarithmic amplifier in an 8-PDIP and 8-SOIC package. These amplifiers can take voltage input from 2.7 V to 5.5 V with a very low 7.5 mA of current needed. A fast-acting CMOS-compatible control pin can put the amp in standby mode with extremely low 150 μA of current. The AD8307 is ideal for conversion of signal level to decibel form applications, radar, and multimeter applications.
