EL2250CS-T7

Overview

The EL2250CS-T7 is a dual high-speed operational amplifier manufactured by Renesas Electronics Corporation, housed in an 8-lead Small Outline (SO) package. It features a -3dB bandwidth of 125MHz and a slew rate of 275V/µs. The device operates on supply voltages ranging from 2.7V to 12V with a typical supply current of 5mA per amplifier. It provides an output current capability of ±100mA and maintains a low offset voltage of 4mV maximum.

Feature Summary

• Voltage feedback architecture supporting reactive feedback networks for analog filtering applications
• Rail-to-rail output swing capability allowing outputs to reach ground without saturation
• Input common mode range extending below the negative supply rail down to 0V

Applications

• Video amplifiers
• A/D drivers
• Line drivers
• Active filtering

Procurement Notes

Verify that the component matches the specific EL2250CS-T7 designation, which indicates the SOIC package variant. Confirm RoHS compliance status as the datasheet notes Pb-free plus anneal options are available. Ensure the supplier documentation references the correct Intersil or Renesas part marking for quality assurance.

Selection Notes

Select this component when single-supply operation at low voltages like +3V or +5V is required alongside high-speed performance. It is suitable for portable applications due to its low power consumption. Consider the 8-pin SO package constraints for thermal management if driving heavy loads near the absolute maximum ratings.

Part Context

This device belongs to the EL2250/EL2450 family of fast single-supply operational amplifiers. The EL2250 specifically denotes the dual-channel configuration, whereas the EL2450 represents the quad-channel version. Both share identical electrical characteristics and pinouts within their respective channel counts.

Replacement Considerations

For single-channel requirements, the EL2150 or EL2157 may be considered. For dual-channel variants with additional features such as power-down modes or output clamps, the EL2257 serves as a functional alternative within the same product family.
