Description for the LOG300
The LOG300 is an integrated analog front end (AFE) consisting of low-noise amplifier (LNA) and a Log Detector block. This device supports an input frequency range from 50Hz to 40MHz and a typical dynamic range of 98dB. The LOG300 is intended for use in applications that require a wide dynamic range of voltage and signal measurement. The Log Detector block of LOG300 supports both single-ended and differential inputs. The low input noise of the integrated LNA, allows measurement of signals as low as 7µVP. The transient output response can be adjusted by tuning the capacitor connected at the Log_Out pin. The integrated frequency detect feature of LOG300 enables users to extract input signal frequency and zero-crossing information.
The LOG300 is available in a 16-pin SOIC and 16-pin VQFN package. The LOG300 is operational from a 3V to 5.25V supply and over the full ambient temperature range of –40°C to +125°C.
