EL2227CSZ

Overview

The EL2227CSZ is a dual, very low noise voltage feedback operational amplifier manufactured by Elantec Semiconductor. It features a -3dB bandwidth of 115MHz at a gain of +2 and is stable for gains of +2 or higher. The device operates on supply voltages ranging from ±2.5V to ±12V with a typical supply current of 4.8mA per amplifier. Key electrical parameters include an input voltage noise density of 1.9nV/√Hz and an input current noise density of 1.2pA/√Hz. It is housed in an 8-pin MSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

Dual channel architecture designed for high-fidelity signal processing
Ultra-low noise performance suitable for weak signal detection
Gain-of-2 stability ensures reliable operation in standard configurations
Low power consumption optimized for battery-operated systems

Applications

ADSL line receiving circuits
HDSLII receiver front-ends
Ultrasound input amplification stages
Wideband instrumentation systems
AGC and PLL active filters

Procurement Notes

Verify the manufacturer origin as Elantec Semiconductor or its successor entities like Intersil/Renesas. Confirm the specific suffix 'CSZ' indicates the MSOP package variant. Check RoHS compliance status against the latest datasheet revision. Ensure availability aligns with current production lifecycles for legacy analog components.

Selection Notes

Select this component when designing circuits requiring minimal noise addition to low-level signals. The dual configuration reduces board space compared to single-channel alternatives. Verify that the required bandwidth exceeds 115MHz at unity gain if higher frequencies are needed. Ensure the application fits within the specified ±2.5V to ±12V supply range constraints.

Part Context

This part belongs to the EL2227 series of dual low-noise amplifiers. It serves as a specialized solution for telecommunications and medical imaging applications where signal integrity is critical. The MSOP packaging allows for compact design in portable devices. It complements other high-speed op-amps by prioritizing noise performance over slew rate.
