LOG112AID .

The LOG112AID is a precision Logarithmic and Log Ratio Amplifier with on-chip 2.5V voltage reference. The versatile integrated circuit computes the logarithm or log ratio of an input current relative to a reference current. VLOGOUT of the LOG112 is trimmed to 0.5V per decade of input current, ensuring high precision over a wide dynamic range of input signals. The LOG112 features a 2.5V voltage reference that may be used to generate a precision current reference using an external resistor. Low DC offset voltage and temperature drift allow accurate measurement of low-level signals over the specified temperature range of -5 to +75°C.
