The output signal at VLOGOUT is trimmed to 0.375V out per decade of input current. If more range is needed, the supply voltage can be increased on the LOG114 and the output can be scaled with one of the available additional amplifiers, if desired. Low dc offset voltage and temperature drift allow accurate measurement of low-level signals over a wide environmental temperature range. The LOG114 is specified over a -5C to +75C temperature range.
