EL5221CY-T7

Instrumentation, Op Amps, Buffer Amps Overview

The EL5221CY-T7 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 to ±120mA. The component is housed in an 8-lead MSOP package and is specified for operation over an ambient temperature range of -40°C to +85°C.

• Immunity to output phase reversal when input voltage remains within specified limits

Instrumentation, Op Amps, Buffer Amps Applications

• TFT-LCD drive circuits
• ADC/DAC buffers
• Portable instrumentation
• Personal communication devices

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'CY' corresponds to the 8-lead MSOP package configuration. Confirm that the '-T7' suffix indicates reel packaging specifications as detailed in Intersil Technical Bulletin TB347. Ensure the procurement matches the RoHS compliant Pb-free plus anneal material set requirements if lead-free soldering compatibility is required for the assembly process.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring unity gain buffering with rail-to-rail signal swing capabilities. Consider the 12MHz bandwidth and 10V/µs slew rate for general-purpose signal conditioning. Evaluate thermal dissipation curves against expected load currents to ensure junction temperatures remain within safe operating limits during continuous operation.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL5221 belongs to a family of low power, high voltage amplifiers that also includes single-channel and quad-channel variants. These devices share similar electrical characteristics but differ in pin counts and package options such as SOT-23 or QFN. The EL5221 specifically integrates two independent buffers into an 8-lead MSOP footprint, optimizing space for portable electronic designs.
