The dynamic range is defi ned as the range over which the may cause permanent damage to the device. Exposure to any Absolute linearity error is within ±1dB. Maximum Rating condition for extended periods may affect device Note 4: Sensitivity is defi ned as the minimum input power required for the reliability and lifetime. linearity error within 3dB of the ideal log-linear transfer curve.
