CA3078AE

Overview

The CA3078AE is a high-gain monolithic operational amplifier from the CA3078 series, manufactured by Renesas Electronics Corporation (formerly Intersil). It delivers milliamperes of output current while consuming microwatts of standby power. The device features externally adjustable operating points and frequency compensation via a single external capacitor. It supports operation with a single 1.5V battery supply. The 'A' variant offers an extended supply voltage range up to ±15V compared to the standard CA3078 limit of ±6V.

Feature Summary

• Low standby power consumption as low as 700nW
• Wide supply voltage range supporting single or dual supplies
• High peak output current capability with short circuit protection
• Adjustable quiescent current for tailored performance

Applications

• Portable electronics
• Medical electronics
• Telemetry systems
• Instrumentation
• Intrusion alarms

Procurement Notes

Verify the specific suffix 'AE' against the manufacturer's official documentation to confirm the temperature range and package type. Confirm that the component is sourced from authorized distributors to ensure authenticity. Check for obsolete status indicators as this part may be superseded by newer equivalents in current catalogs.

Selection Notes

Select the CA3078AE when ultra-low power consumption is critical alongside moderate bandwidth requirements. Choose this device over standard op-amps if the design requires adjustable quiescent current to balance speed and power dissipation. Ensure the application fits within the specified supply voltage limits and thermal constraints for the selected package.

Part Context

This component belongs to the CA3078 family of micropower operational amplifiers originally developed by Intersil. The CA3078A variant provides enhanced supply voltage tolerance compared to the base CA3078 model. The series is designed for applications requiring long battery life without significant sacrifice in signal processing speed or gain.

Replacement Considerations

Public confirmed substitute part numbers include ICL7611, ICL7612, CA5420A, CA3140, and CA3160.
