The LOG300 comes with an internal offset correction loop (OCL) designed to correct for any small offset voltage errors due to external factors or due to the input gain blocks mismatch. The LOG300 internal gain blocks offer very high gain; therefore, any small error at the input is sufficient to saturate the log output.
The Offset_Cap (see Section 6) sets the time constant of the offset correction loop. Set the value of the OCL pole to less than the incoming signal frequency so that the OCL does not respond to the incoming signal. Use the following formula to calculate the value of Offset_Cap based on the frequency of the incoming signal.
