EL2227CS-T13

Overview

The EL2227CS-T13 is a dual, very low noise voltage feedback operational amplifier manufactured by Renesas Electronics Corporation. It features a typical supply current of 4.8mA per amplifier and operates within a supply voltage range of ±2.5V to ±12V. The device provides a -3dB bandwidth of 115MHz at a gain of +2 and maintains stability at gains of +2 or higher. Key electrical specifications include an input offset voltage of 3mV, an open-loop gain of 87dB, and a common-mode rejection ratio of 60dB. Input bias current is typically 9µA, with a slew rate of 50V/µs. The component is housed in an 8-lead SOIC package and supports operation from -40°C to +85°C.

Feature Summary

• Dual-channel architecture designed for line receiving applications requiring minimal signal degradation
• Voltage feedback topology enabling the use of capacitors in the feedback path for active filters and integrators
• Low power consumption with moderate supply current draw suitable for battery-operated systems
• High output drive capability allowing operation into low impedance loads

Applications

• ADSL receivers
• HDSLII receivers
• Ultrasound input amplifiers
• Wideband instrumentation
• AGC and PLL active filters

Procurement Notes

Verify that the ordering suffix matches the required tape and reel configuration, as standard packaging differs from bulk tube options. Confirm the specific package variant corresponds to the design requirements, noting that the CS designation indicates an 8-lead SOIC package. Ensure compliance with RoHS standards if lead-free processing is mandated for the assembly process.

Selection Notes

Select this component when high-speed performance combined with ultra-low noise characteristics is critical for signal integrity. The voltage feedback structure is preferred over current feedback topologies when flexibility in feedback element selection, such as integrating capacitors, is necessary. Evaluate thermal dissipation constraints carefully, as power limits vary between package types under maximum ambient temperatures.

Part Context

This part belongs to the EL2227 series of dual amplifiers produced by Intersil, now part of Renesas Electronics. The series includes variants in both MSOP and SOIC packages. The EL2227 family is engineered using a proprietary high-speed complementary bipolar process to deliver high bandwidth while maintaining low distortion and power consumption levels.
