Product Summary
The LOG102AID is a logarithmic and log ratio amplifier. The LOG102AID is a versatile integrated circuit that computes the logarithm or log ratio of an input current relative to a reference current. The LOG102AID 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.
