Low power, 95dB dynamic range, logarithmic detector

The LOG305 is a Log Detector / RSSI Detector with very low power consumption. This device supports an input frequency from 200kHz to 100MHz and a typical dynamic range of 95dB. The LOG305 can support beyond these frequencies at reduced sensitivity. The LOG305 is intended for use in applications that require a wide dynamic range of voltage and signal measurement. This device supports single ended inputs and unipolar or bipolar supplies.

The LOG305 is available in a 6-pin DRV package. The LOG305 is operational from a 2.7V to 5.25V supply and over the full ambient temperature range of –40°C to +125°C.
