Overview
The EL2270CS-T7 is a dual current-feedback operational amplifier manufactured by Intersil (Renesas). It achieves a -3dB bandwidth of 70MHz at a gain of +1 while consuming only 1mA of supply current per amplifier. The device operates with dual supplies ranging from ±1.5V to ±6V, or single supplies from +3V to +12V. It can output 55mA while swinging to ±4V on ±5V supplies. Key specifications include a slew rate of 800V/µs and differential gain/phase errors of 0.15%/0.15° into 150Ω.
Feature Summary
- Dual topology configuration for space-efficient designs
- Low power consumption with 1mA supply current per amplifier
- High-speed performance with 70MHz bandwidth and 800V/µs slew rate
- Capable of high output current drive up to 55mA
Applications
- Low power cable drivers
- HDSL applications
- RGB signal processing
Procurement Notes
Verify the specific suffix 'T7' against official Renesas documentation to confirm tape-and-reel packaging requirements. Ensure the ordering part number matches the exact package style and temperature range specified in the datasheet. Cross-reference manufacturer identifiers as Intersil assets are now managed by Renesas.
Selection Notes
Select this component when board space is critical but high speed is required. It serves as an alternative to the EL2170 family for dual-channel needs. Consider the EL2180 family if higher bandwidth is necessary despite increased power consumption. Verify that the application requires current-mode feedback characteristics rather than voltage-feedback topologies.
Part Context
The EL2270 belongs to the EL2170 series of current-feedback amplifiers. This series includes single (EL2170), dual (EL2270), and quad (EL2470) variants. The CS suffix indicates a commercial temperature range and SOIC package. These amplifiers are designed for applications requiring low power and high speed simultaneously.
FAQ
