LOG100JP-2

Overview

The LOG100JP-2 is a precision logarithmic and log ratio amplifier manufactured by Texas Instruments. It is housed in a hermetically sealed 14-pin ceramic dual in-line package (CDIP). The device operates as a single-function circuit designed for high-accuracy signal processing applications requiring logarithmic conversion or ratio measurement capabilities.

Feature Summary

• Hermetically sealed ceramic construction for environmental stability
• Precision logarithmic and log ratio amplification functionality
• Single-channel operational architecture

Applications

• High-dynamic-range signal processing
• Logarithmic conversion circuits
• Log ratio measurement systems

Procurement Notes

Verify the specific suffix -2 indicates the hermetically sealed ceramic variant distinct from standard plastic packages. Confirm RoHS compliance status as sources indicate non-compliance due to lead content. Ensure the procurement channel supports through-hole mounting requirements for the CDIP-14 form factor.

Selection Notes

Select this component when hermetic sealing is required for reliability in harsh environments. Choose over plastic variants if radiation resistance or long-term stability under extreme conditions is necessary. Verify that the through-hole mounting style aligns with the target PCB design constraints.

Part Context

This part belongs to the LOG100 family of logarithmic amplifiers from Texas Instruments, originally developed by Burr-Brown. The LOG100 series provides precision analog computation functions. The JP-2 designation specifically denotes the military-grade or high-reliability ceramic DIP version within this product line.

Replacement Considerations

Direct substitutes include the LOG100JP and LOG100JG. For plastic package equivalents, consider the LOG100J or LOG100N, though hermeticity will differ. Cross-reference with LOG101 or LOG102 only if functional differences are acceptable.
