AD8317ACPZ-R7 Logarithmic Amplifier

AD8317ACPZ-R7 Logarithmic Amplifier

The AD8317ACPZ-R7 is a high-speed, wide dynamic range logarithmic amplifier designed for use in RF and microwave signal chains. It operates over a broad frequency range and provides accurate RF signal power measurement. This device converts an RF input signal to a corresponding DC output voltage that is proportional to the logarithm of the input signal's amplitude, making it ideal for applications requiring power monitoring or signal leveling.
