EL2270CSZ

Overview

The EL2270CSZ is a dual-channel high-speed current-feedback operational amplifier manufactured by Renesas Electronics, formerly Intersil. It operates within a supply voltage range of 5V to 24V single or ±2.5V to ±12V dual supplies. Key electrical parameters include a slew rate of 50 V/µs, a voltage gain of 87 dB, and an input bias current of 9 µA. The device features low noise characteristics with an input voltage noise density of 1.9 nV/√Hz and input current noise density of 1.2 pA. It is housed in an SOIC-8 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing two independent high-speed amplification paths within a compact footprint.
• High slew rate capability enabling rapid signal transitions for demanding video and communication applications.
• Low noise performance suitable for precision signal conditioning and sensitive analog front-end circuits.
• Flexible power supply operation supporting both single and dual rail configurations for system integration.

Applications

• Video signal processing and distribution systems
• High-speed data acquisition equipment
• Test and measurement instrumentation amplifiers
• Current-to-voltage conversion circuits

Procurement Notes

Verify the specific suffix 'CSZ' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS compliance status. Ensure the source document explicitly lists this part number as active or limited availability. Cross-reference the manufacturer name between Renesas and Intersil records to avoid confusion with legacy stock. Confirm the package type matches the design requirements before finalizing procurement orders.

Selection Notes

Select this component when dual-channel high-speed amplification is required with low noise specifications. The current-feedback topology offers superior slew rate performance compared to voltage-feedback alternatives at similar bandwidths. Consider the SOIC-8 package constraints for PCB layout and thermal management. Evaluate the 50 V/µs slew rate against the maximum signal frequency requirements of the target application to ensure adequate response time without distortion.

Part Context

This component belongs to the EL2227 series of high-speed operational amplifiers produced by Renesas Electronics. The series includes variants such as the EL2227CYZ, which shares similar electrical characteristics but utilizes an MSOP-8 package instead of the SOIC-8 form factor found in the EL2270CSZ. These devices are designed for applications requiring fast transient response and low power consumption in portable or battery-operated systems.
