EL5221CY

Instrumentation, Op Amps, Buffer Amps Overview

The EL5221CY is a dual, low power, high voltage rail-to-rail input-output buffer manufactured by Renesas Electronics Corporation. It operates on supply voltages ranging from 4.5V to 16.5V with a typical supply current of 500µA per channel. The device features a -3dB bandwidth of 12MHz and a slew rate of 10V/µs. It provides an output drive capability of 30mA (sink and source) and includes short circuit current limiting up to ±120mA. The component is housed in an 8-lead MSOP package and is specified for operation over a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. Confirm that the EL5221CY variant matches the required pinout and thermal characteristics for the target application. Ensure compatibility with existing PCB footprints designed for the 8-lead MSOP package before finalizing procurement decisions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual buffer with rail-to-rail performance and low power consumption is required. It is suitable for applications operating within a 4.5V to 16.5V supply range. Consider the 12MHz bandwidth and 10V/µs slew rate for signal integrity requirements. Verify that the 8-lead MSOP package fits the available board space and thermal management constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL5221 is part of a family of low power, high voltage rail-to-rail input-output amplifiers. This family includes single-channel (EL5120) and quad-channel (EL5420) variants. All members share similar electrical characteristics, including 12MHz bandwidth and 500µA per channel current consumption. The EL5221 specifically provides two independent buffers in a compact package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pin compatibility and electrical specifications if replacing with other models in the EL5120 or EL5420 families.
