EL5221CYZ-T13

Overview

The EL5221CYZ-T13 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 while consuming only 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) with short circuit current limits of ±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.

Feature Summary

• Rail-to-rail input and output capability providing maximum dynamic range at any supply voltage
• Low power consumption with 500µA supply current per buffer channel
• High output drive capability of 30mA with internal short-circuit protection

Applications

• TFT-LCD drive circuits
• ADC/DAC buffers
• Portable instrumentation
• Active filters

Procurement Notes

Verify the specific ordering suffix T13 indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status as manufacturing processes may vary. Check for lead-free plus anneal specifications if required for soldering operations. Ensure the supplier provides valid datasheets matching the FN7187.2 revision. Validate that the part number corresponds to the 8-lead MSOP package configuration.

Selection Notes

Select this component for applications requiring unity gain buffering with rail-to-rail performance. Consider the 12MHz bandwidth and 10V/µs slew rate for signal integrity requirements. Evaluate the 500µA per channel current consumption against system power budgets. Verify compatibility with single or split supply configurations within the 4.5V to 16.5V operating range.

Part Context

The EL5221 belongs to a family of low power, high voltage rail-to-rail input-output amplifiers. Similar devices include the EL5120, EL5220, and EL5420, which offer varying channel counts. These components are designed for general-purpose applications where low power consumption and wide dynamic range are critical. The EL5221 specifically integrates two independent buffers in a compact package.
