EL5127CY

Instrumentation, Op Amps, Buffer Amps Overview

The EL5127CY is a low-power, high-voltage rail-to-rail input/output buffer amplifier manufactured by Intersil. It integrates four independent circuits within a single package, designed for reference voltage buffering applications. Key electrical specifications include a slew rate of 2.2V/µs, a -3dB bandwidth of 2.5 MHz, and an input bias current of 2 nA. The device features rail-to-rail output capability and operates in a 10-MSOP package. This component is classified as obsolete.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the obsolete status of the EL5127CY before procurement planning. Confirm availability through authorized distributors or surplus suppliers. Ensure compatibility with existing PCB footprints and thermal requirements. Check for lead-free compliance if required by specific manufacturing standards. Validate that the 10-MSOP package matches the target assembly process.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple buffered outputs are required from a single source. Consider the 2.5 MHz bandwidth and 2.2V/µs slew rate for signal integrity needs. Evaluate the low input bias current for high-impedance sensor interfaces. Compare against newer quad buffer alternatives if long-term supply assurance is critical.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL5127 belongs to a family of low-power, high-voltage rail-to-rail buffers that includes the EL5227, EL5327, and EL5427. These devices share similar architectural characteristics but may differ in specific performance metrics or packaging options. The EL5127CY specifically denotes the quad-channel variant in a 10-MSOP package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements should be identified through manufacturer cross-reference guides or functional equivalents with compatible pinouts and electrical specifications.
