Rev. F | Page 13 of 24
For zero-signal conditions, all the detector output currents are
equal. For a finite input of either polarity, their difference is
converted by the output interface to a single-sided unipolar
current, nominally scaled 2 μA/dB (40 μA/decade), at the
output pin BFIN. An on-chip resistor of ~3 kΩ, R1, converts
this current to a voltage of 6 mV/dB. This is then amplified by a
factor of 4 in the output buffer, which can drive a current of up
to 25 mA in a grounded load resistor. The overall rise time of
the AD8310 is less than 15 ns. There is also a delay time of
about 6 ns when the log amp is driven by an RF burst, starting
at zero amplitude.
When driving capacitive loads, it is desirable to add a low value
of load resistor to speed up the return to the baseline; the buffer
is stable for loads of a least 100 pF. The output bandwidth can
be lowered by adding a grounded capacitor at BFIN. The time-
constant of the resulting single-pole filter is formed with the
3 kΩ internal load resistor (with a tolerance of 20%). Therefore,
to set the 3 dB frequency to 20 kHz, use a capacitor of 2.7 nF.
Using 2.7 μF, the filter corner is at 20 Hz.
