MC1496P1

Overview

The MC1496P1 is a balanced modulator and demodulator integrated circuit manufactured by onsemi, housed in a 14-pin PDIP package. Designed for RF applications, it operates with a maximum frequency of 300 MHz and supports FM modulation formats. The device functions as an RF IC where the output voltage represents the product of an input signal and a switching carrier function. It requires a supply current of 5 mA and is rated for operation within a temperature range extending to 70°C, with power dissipation specified at 33 mW.

Feature Summary

• Provides excellent carrier suppression capabilities for balanced modulation tasks
• Features high common mode rejection ratios typical of balanced architectures
• Supports adjustable gain and signal handling characteristics
• Integrates eight active transistors within a single compact package

Applications

• Suppressed carrier modulation systems
• Amplitude modulation circuits
• Synchronous detection applications
• FM detection stages
• Phase detection implementations

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors due to potential availability constraints. Confirm package integrity and pin alignment against the 14-PDIP specification before integration. Review datasheet revisions for any historical manufacturing changes. Ensure thermal management aligns with the 33 mW dissipation rating during system design validation.

Selection Notes

Select this component when balanced modulation with high carrier suppression is required for frequencies up to 300 MHz. Consider the PDIP package constraint for prototyping or specific board layout requirements. Evaluate the 5 mA supply current against system power budgets. Compare performance metrics such as common mode rejection against alternative solutions if higher frequency ranges are necessary.

Part Context

The MC1496 series represents a family of balanced modulators and demodulators designed for linear multiplication of signals. Variants include SOP and DIP packages, with the MC1496P1 specifically utilizing the plastic dual in-line configuration. This component belongs to onsemi's RF and wireless portfolio, serving foundational roles in communication hardware requiring precise signal mixing and demodulation.

Replacement Considerations

The MC1496BDG is a documented equivalent variant within the same product family offering similar balanced modulation functionality. Verify pin compatibility and package dimensions when substituting between PDIP and SOIC formats. Cross-reference electrical specifications to ensure operational parameters remain within acceptable limits for the target application.
