Overview
The EL2227CSZ-T7 is a dual, very low noise voltage feedback operational amplifier manufactured by Renesas/Intersil. It features a -3dB bandwidth of 115MHz at a gain of +2 and is stable for gains of +2 or higher. The device exhibits a voltage noise density of 1.9nV/sqrt(Hz) and a current noise density of 1.2pA/sqrt(Hz). It operates from supply voltages ranging from ±2.5V to ±12V with a quiescent current of 4.8mA per amplifier. The component is housed in an 8-pin SOIC package.
Feature Summary
- Dual channel architecture designed for line receiving applications
- Ultra-low input voltage and current noise specifications
- High bandwidth performance suitable for wideband signal processing
- Stable operation at a closed-loop gain of +2
Applications
- ADSL receivers
- HDSLII receivers
- Ultrasound input amplifiers
- Wideband instrumentation
- AGC and PLL active filters
Procurement Notes
Verify the specific suffix 'T7' against official datasheets to confirm tape-and-reel packaging requirements. Confirm that the 'CSZ' designation corresponds to the SOIC-8 package variant rather than MSOP. Ensure compatibility with the required ±2.5V to ±12V supply range during integration.
Selection Notes
Select this component when designing circuits requiring minimal signal degradation in high-frequency analog paths. The low noise profile makes it appropriate for detecting very low amplitude signals. Verify that the system power budget accommodates the 4.8mA per amplifier consumption while maintaining thermal stability within the specified operating temperature range.
Part Context
This part belongs to the EL2227 series of dual low-noise amplifiers. It serves as a specialized solution for telecommunications and medical imaging front-ends where signal integrity is critical. The family includes variants with different packaging options, such as MSOP and SOIC, to accommodate various board space constraints.
Replacement Considerations
Consult official substitution guides for equivalent dual low-noise amplifiers. Verify pinout compatibility and electrical parameter alignment before replacing the component in existing designs.
