EL5120TIWTZ-T7

Overview

The EL5120TIWTZ-T7 is a single-channel, high-voltage operational amplifier manufactured by Renesas Electronics Corporation (formerly Intersil). It features rail-to-rail input and output capabilities with an operating voltage range of 4.5V to 19V. The device provides a gain-bandwidth product of 8MHz and a slew rate of 12V/µs. It typically consumes 750µA of supply current and supports continuous output currents up to ±70mA with short-circuit protection up to ±200mA. The component operates within an ambient temperature range of -40°C to +125°C and is housed in a 5-lead TSOT package.

Feature Summary

• Rail-to-rail input and output capability with common-mode input range extending beyond the supply rails.
• Unity-gain stable design suitable for direct feedback configurations without external compensation.
• Built-in thermal shutdown protection that automatically disables outputs during overheating events.
• High output drive capability supporting ±70mA continuous current and ±200mA short-circuit current.

Applications

• TFT-LCD panel VCOM amplifiers and static gamma buffers
• Touch-screen display signal conditioning
• Sampling ADC amplifiers
• Active filters and signal processing circuits

Procurement Notes

Verify the manufacturer origin, as the part was originally produced by Intersil before its acquisition by Renesas. Confirm the specific package marking 'BESA' matches the 5 Ld TSOT configuration. Ensure compliance with RoHS standards and check for Moisture Sensitivity Level requirements relevant to your assembly process. Validate that the ordering suffix corresponds to the correct reel specifications.

Selection Notes

Select this component when designing circuits requiring high-voltage operation up to 19V with low power consumption. It is appropriate for applications needing rail-to-rail signal swing and fast transient response. Consider the thermal resistance characteristics if operating near maximum junction temperatures. Ensure load capacitance does not exceed 1nF without isolation techniques to maintain stability.

Part Context

This operational amplifier belongs to the EL5120T family, designed for high-performance analog signal processing. Originally developed by Intersil, the product line continues under Renesas Electronics Corporation. The device is engineered for portable and battery-powered applications where efficiency and dynamic range are critical. It serves as a versatile solution for driving displays and interfacing with data converters.

Replacement Considerations

Direct pin-compatible replacements should be verified against the official datasheet. Cross-reference electrical parameters such as bandwidth, slew rate, and supply voltage limits. Ensure any substitute maintains the same 5-lead TSOT package dimensions and thermal characteristics. Consult manufacturer documentation for recommended migration paths or updated part numbers.
