Overview
The CLC449AJE is a monolithic current feedback operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC package. It features a bandwidth of 1.1 GHz and a slew rate of 2000 V/µs. The device operates with a supply voltage range of ±2.5V to ±17V and consumes 6 µA of quiescent current per channel. It supports single or dual power supplies and provides high-speed signal processing capabilities suitable for wideband applications.
Feature Summary
- Ultra-wideband performance with 1.1 GHz bandwidth
- High slew rate of 2000 V/µs for fast transient response
- Low quiescent current consumption of 6 µA
- Monolithic construction for stability and reliability
Applications
- Video signal processing
- Wideband amplification
- RF front-end circuits
- Test and measurement equipment
Procurement Notes
Verify the manufacturer origin, as the component was originally developed by National Semiconductor before its acquisition by Texas Instruments. Confirm the package type is 8-SOIC and check RoHS compliance status, as older revisions may not meet current environmental standards. Ensure the specific suffix 'AJE' matches the required temperature grade and packaging format for your design requirements.
Selection Notes
Select this component when high-speed voltage slewing and wide bandwidth are critical. It is suitable for applications requiring low power consumption alongside high-frequency operation. Compare against other current feedback amplifiers if higher gain bandwidth product is needed, but note that this part offers a balance of speed and low current draw.
Part Context
This amplifier belongs to the CLC4xx series of ultra-wideband monolithic op amps from National Semiconductor, now part of Texas Instruments. The series includes variants like CLC426 and CLC446, sharing similar architectural principles but differing in specific bandwidth and performance metrics. The CLC449AJE represents a high-performance option within this lineage.
Replacement Considerations
Check for direct equivalents such as the CLC446AJE or CLC426AJE if pin compatibility is required, though bandwidth differences exist. Verify if newer generations from Texas Instruments offer improved specifications while maintaining the same footprint.
