The LOG104 is a versatile integrated circuit that computes the logarithm or log ratio of an input current relative to a reference current.
●The LOG104 is tested over a wide dynamic range of input signals. In log ratio applications, a signal current can come from a photodiode, and a reference current from a resistor in series with a precision external reference.
●The output signal at VOUT is trimmed to 0.5V per decade of input current, allowing seven decades of input current, dynamic range.
●Low DC offset voltage and temperature drift allow accurate measurement of low-level signals over a wide environmental temperature range. The LOG104 is specified over the temperature range 5°C to +75°C, with operation over 40°C to +85°C.
