CA3102M

Overview

The CA3102M is a dual high-frequency differential amplifier manufactured by Renesas Electronics Corporation, housed in a 14-lead narrow body Small Outline Integrated Circuit (SOIC) package. Designed for low power applications up to 500MHz, the device integrates two independent differential amplifiers with associated constant current transistors on a common monolithic substrate. It features a separate substrate connection for design flexibility and operates across the full military temperature range of -55°C to 125°C.

Feature Summary

• Monolithic construction provides close electrical and thermal matching between the two channels
• Features two independent differential amplifiers with independently accessible inputs and outputs
• Includes a separate substrate connection for enhanced design flexibility

Applications

• VHF Amplifiers
• VHF Mixers
• IF Amplifiers
• Product Detectors
• Synthesizers

Procurement Notes

Verify that the ordering suffix 'M' corresponds specifically to the 14-lead SOIC package variant. Confirm the manufacturer designation as Renesas Electronics Corporation or Intersil Americas Inc., noting historical branding transitions. Ensure the component meets RoHS compliance requirements if applicable to the specific production lot.

Selection Notes

Select this component when matched performance between two differential channels is required due to its monolithic substrate construction. The device is suitable for designs requiring operation from DC up to 500MHz with low 1/f noise characteristics. Consider the separate substrate terminal for optimal isolation and biasing configurations in high-frequency circuits.

Part Context

This part belongs to the CA3102 series of dual high-frequency differential amplifiers. While originally introduced by Intersil, the product line is now managed under Renesas Electronics Corporation. The series includes variants such as the CA3102E in a PDIP package and the CA3102MZ in a Pb-free SOIC package, all sharing the same core internal circuit topology.
