  • Description

    The AD646J is a complete monolithic logarithmic amplifier that falls under the product category of IC Chips. It provides a dynamic range of up to 50 dB for frequencies ranging from DC to 120 MHz. By cascading two AD640s, the dynamic range can be extended to 95 dB at reduced bandwidth. The AD646J utilizes a successive detection scheme to generate an output current that is proportional to the logarithm of the input voltage. It is laser calibrated to maintain high accuracy over the full military temperature range and can operate with supply voltages ranging from ±4.5 V to ±7.5 V.
