NOTES
1Minimum and maximum specified limits on parameters that are guaranteed but not tested are six sigma values.
2The 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
termination corresponds to an input of 0.2236 V rms. Hence, the relationship between dBV and dBm is a fixed
offset of +13 dBm in the special case of a 50
termination.
3Due to the extremely high Gain Bandwidth Product of the AD8309, the output of either LMHI or LMLO will be unstable for levels below –78 dBV (–65 dBm, re 50
).
Specifications subject to change without notice.
(VS = +5 V, TA = +25 C, unless otherwise noted)
