Normal logarithmic amplifiers are limited in dynamic range in
the voltage-input mode by their input-offset voltage. The
built-in temperature compensation and convenience features
of the ICL8048 can be extended to a voltage-input dynamic
range of close to 6 decades by using the ICL7650S to offset-
null the ICL8048, as shown in Figure 6. The same concept
can also be used with such devices as the HA2500 or
HA2600 families of op amps to add very low offset voltage
capability to their very high slew rates and bandwidths. Note
that these circuits will also have their DC gains, CMRR, and
PSRR enhanced.
