EL5257IS

Overview

The EL5257IS is a dual-channel voltage feedback operational amplifier manufactured by Elantec Semiconductor. It features a high slew rate of 700 V/µs and a gain-bandwidth product of 210 MHz, with a -3 dB bandwidth of 600 MHz. The device operates on a supply voltage range of 5 V to 12 V and draws 6 mA of supply current for both channels. It provides an output current of 140 mA per channel and has a maximum input offset voltage of 500 µV. The component is housed in an 8-MSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing two independent voltage feedback amplifiers within a single compact surface-mount package.
• High-speed performance characterized by a 700 V/µs slew rate and 600 MHz bandwidth for rapid signal processing.
• Robust output drive capability delivering 140 mA per channel to support demanding load requirements.

Applications

• Video buffering and signal conditioning
• High-speed data acquisition systems
• Active filtering circuits

Procurement Notes

Verify the manufacturer status as the EL5257 series may be discontinued or superseded by newer equivalents. Confirm the specific suffix 'IS' matches the required industrial temperature grade and package variant. Cross-reference with authorized distributors to ensure authenticity and check for recommended replacement components if the original part is no longer in active production.

Selection Notes

Select this component when a dual-channel configuration is required alongside high slew rates and significant output current drive capabilities. Ensure the 5 V to 12 V supply voltage range aligns with the system power rails. Consider the 8-MSOP package dimensions for PCB layout constraints and verify that the 600 MHz bandwidth meets the application's frequency response requirements.

Part Context

The EL5257IS belongs to the EL5257 family of dual high-speed operational amplifiers designed for video and broadband applications. This series integrates two independent amplifiers into a small footprint, offering high output current and wide bandwidth. The 'IS' designation typically indicates the industrial temperature range and MSOP packaging, distinguishing it from other variants in the lineup.

Replacement Considerations

LT1816CMS8#TRPBF and LT1816IMS8#PBF are documented similar replacements for the EL5257 series.
