AD8310–SPECIFICATIONS
The input level is specified in “dBV” since logarithmic amplifiers respond strictly to voltage, not power. 0 dBV corresponds to a sinusoidal single-frequency input of
1 V rms. A power level of 0 dBm (1 mW) in a 50
offset of 13 dBm in the special case of a 50
Guaranteed but not tested; limits are specified at six sigma levels.
