CA3054MZ

Overview

The CA3054MZ is a dual independent differential amplifier housed in a 14-lead SOIC package. It integrates six NPN transistors on a common monolithic substrate, providing close electrical and thermal matching for dual-channel applications. The device operates from DC to 120MHz with an fT exceeding 300MHz. Key specifications include a maximum input offset voltage of ±5mV and an operating temperature range of 0°C to 85°C.

Feature Summary

• Monolithic construction ensures close electrical and thermal matching between the two independent amplifiers.
• Bias and load resistors are omitted to provide maximum application flexibility.
• General purpose NPN transistors exhibit low 1/f noise characteristics.

Applications

• Dual Sense Amplifiers
• Dual Schmitt Triggers
• IF Amplifiers (Differential and/or Cascode)
• Product Detectors
• Synchronous Detectors

Procurement Notes

Verify that the ordering suffix M96 or MZ96 indicates tape and reel packaging, whereas the standard MZ suffix denotes tube packaging. Confirm RoHS compliance status as Intersil Pb-free plus anneal products utilize specific material sets compatible with both SnPb and Pb-free soldering operations. Ensure the substrate pin is connected to a voltage more negative than any collector voltage to maintain isolation.

Selection Notes

Select this component when matched performance between two channels is required due to its monolithic substrate design. It is suitable for applications requiring low 1/f noise and operation up to 120MHz. The absence of internal bias and load resistors allows designers to customize circuit parameters for specific gain and impedance requirements.

Part Context

The CA3054 series was originally manufactured by Harris Corporation and later acquired by Intersil Americas Inc., which continues to produce the device. Renesas Electronics Corporation now markets the part under the CA3054MZ designation. The datasheet FN388.6 documents the technical specifications and typical performance curves for this integrated circuit.

FAQ

How must the substrate terminal be connected?

The substrate must be connected to a voltage more negative than any collector voltage to maintain isolation between transistors and provide normal transistor action. It should also be maintained at signal ground via a capacitor.

What is the function of Terminal 10?

Terminal 10 of the CA3054 is not used.
