The Texas Instruments LOG112AID is a versatile integrated circuit designed to compute the logarithm or log ratio of an input current relative to a reference current. It features an on-chip 2.5V voltage reference, which can also be used externally. The output voltage is precisely trimmed to 0.5V per decade of input current, ensuring high precision across a wide dynamic range of input signals.
Key electrical specifications include a high accuracy of 0.2% FSO, a wide input dynamic range spanning 7.5 decades from 100pA to 3.5mA, and a low quiescent current of 1.75mA. The device operates over a wide supply voltage range of ±4.5V to ±18V.
Packaged in a 14-pin SOIC (D) package, the LOG112AID is suitable for operation in temperatures ranging from -40°C to 85°C. Its design makes it ideal for applications such as logarithmic and log ratio calculations in communication, analytical, medical, industrial, test, and general instrumentation systems. It is also used for photodiode signal compression, analog signal compression before A/D converters, and absorbance or optical density measurements.
