LOG100JP-4

Overview

The LOG100JP-4 is a precision logarithmic and log-ratio amplifier manufactured by Texas Instruments. It integrates two logarithmic amplifiers followed by a high-accuracy differential amplifier to convert current signals into a single-ended voltage representing the log-compressed ratio of two currents. The device features an internally set log amplifier ratio for current-to-voltage conversion. It includes an uncommitted high-speed amplifier allowing output configuration for differential or filtered responses, supporting versatile signal processing applications in analog systems.

Feature Summary

• Integrates dual logarithmic amplifiers with a high-accuracy differential stage for precise log-compressed ratio conversion
• Features an internally set logarithmic ratio for standardized current-to-voltage signal processing
• Includes an uncommitted high-speed operational amplifier enabling flexible differential or filtered output configurations

Applications

• Precision logarithmic signal conditioning
• Log-ratio current measurement systems
• Analog signal compression circuits

Procurement Notes
