APPLICATIONS INFORMATION
FAST LOGARITHMIC AMPLIFIER
The circuit in Figure 19 is a modification of a standard
logarithmic amplifier configuration. Running the SSM2212 at
2.5 mA per side (full scale) allows a fast response with a wide
dynamic range. The circuit has a 7 decade current range and a
5 decade voltage range, and it is capable of 2.5 µs settling time to
1% with a 1 V to 10 V step. The output follows the equation:
IN
REF

q
kT
R
RR
V ln

23 +
=
To compensate for the temperature dependence of the kT/q term, a
resistor with a positive 0.35%/°C temperature coefficient is chosen
for R
2
. The output is inverted with respect to the input and is
nominally −1 V/decade using the component values indicated.
