LOG112AIDR Description

Short technical summary and product information.

The LOG112AIDR from Texas Instruments is a versatile integrated circuit designed to compute the logarithm or log ratio of an input current relative to a reference current. It boasts high accuracy with 0.2% FSO over 5 decades and a wide input dynamic range from 100pA to 3.5mA.

This logarithmic amplifier operates with a low quiescent current of 1.75mA and supports a wide supply range of ±4.5V to ±18V. It includes an on-chip 2.5V voltage reference that can also be used externally. The output voltage is trimmed to 0.5V per decade of input current, ensuring precise measurements.

The LOG112AIDR is available in a 14-pin SOIC package and operates within a temperature range of -40°C to 85°C. Its features make it suitable for applications such as communication, analytical instruments, medical devices, industrial test equipment, and general instrumentation.

Key specifications include a 7.5-decade input dynamic range, 0.2% FSO accuracy, and a ±4.5V to ±18V supply range. The device is designed for ease of use and provides complete logarithmic function scaling.
