LOG2112AIDWR

The LOG2112AIDWR from Texas Instruments is a dual precision logarithmic and log ratio amplifier designed for high-performance applications. This device features an impressive input dynamic range of 7.5 decades, enabling it to handle signals from 100pA to 3.5mA.

With a high accuracy of 0.2% Full Scale Output (FSO) over 5 decades, the LOG2112AIDWR ensures precise signal processing. It operates over a wide supply voltage range of ±4.5V to ±18V and maintains a low quiescent current of 1.75mA. The amplifier includes an on-chip 2.5V voltage reference, simplifying circuit design.

Packaged in a 16-pin SOIC (DW) package, the LOG2112AIDWR is suitable for surface mounting. Its operating temperature range is -40°C to 85°C. This amplifier is ideal for applications such as communication, analytical instruments, medical devices, industrial controls, and general test equipment where logarithmic signal compression or measurement is required.

Key features include ease of use, complete function integration, and output scaling capabilities. The device is well-suited for compressing analog signals before they enter an analog-to-digital converter, or for applications like photodiode signal conditioning, absorbance measurement, and optical density measurement.
