CA3078AM

Overview

The CA3078AM is a micropower operational amplifier manufactured by Rochester Electronics. It features high gain and delivers milliamperes of output current while consuming only microwatts of standby power. The device allows for externally adjustable operating points and frequency compensation via a single external capacitor. Designed for low-power applications, it supports operation with a single 1.5V battery and includes output short-circuit protection.

Feature Summary

• Extremely low standby power consumption
• High peak output current capability
• Externally adjustable quiescent current
• Output short-circuit protection

Applications

• Portable electronics powered by single batteries
• Telemetry systems requiring low power
• Medical electronics devices
• Intrusion alarm circuits
• Precision instrumentation

Procurement Notes

Verify the specific manufacturer designation and lot codes on the component marking against official distributor documentation. Confirm that the part meets the required temperature range and electrical specifications for your design before integration.

Selection Notes

Select this component when ultra-low standby power is critical alongside moderate output drive requirements. Ensure the design accommodates the need for an external compensation capacitor to tailor frequency response and slew rate according to application needs.

Part Context

This part belongs to the CA3078 family of micropower operational amplifiers. It is characterized by its ability to operate from very low supply voltages, such as a single 1.5V battery, making it suitable for energy-constrained environments where traditional op-amps would drain power too quickly.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives. Verify that any replacement maintains the same micropower characteristics and output current capabilities to ensure circuit functionality remains unchanged.
