EL5144CW-T7

Overview

The EL5144CW-T7 is a single-channel voltage feedback operational amplifier manufactured by Renesas Electronics. It utilizes CMOS technology and is housed in an SOT-23-5 surface-mount package. The device operates within a supply voltage range of 4.75 V to 5.25 V, consuming 8.8 mA of quiescent current. Key electrical specifications include a gain-bandwidth product of 60 MHz, a slew rate of 200 V/µs, an input offset voltage of 25 mV, and an input bias current of 100 nA. It provides a common-mode rejection ratio of 47 dB and a power supply rejection ratio of 50 dB. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• High-speed performance with a 200 V/µs slew rate for rapid signal transitions
• Rail-to-rail output capability for maximum dynamic range utilization
• Compact SOT-23-5 packaging suitable for space-constrained designs

Applications

• Video buffering and signal conditioning circuits
• High-speed data acquisition systems
• Portable instrumentation requiring low power consumption

Procurement Notes

Verify the manufacturer designation as Renesas Electronics or Intersil on official documentation. Confirm the package type is SOT-23-5 and the channel count is single. Ensure the part status is reviewed as it may be discontinued. Check export restrictions if applicable to your region. Validate that the specific suffix matches the required tape-and-reel configuration.

Selection Notes

Select this component when a high slew rate and wide bandwidth are required in a small footprint. It is suitable for applications needing rail-to-rail output swing under a single 5V supply. Consider the 25 mV input offset voltage for precision requirements. Evaluate the 8.8 mA supply current against system power budgets. Ensure the operating temperature range meets environmental conditions.

Part Context

This part belongs to the EL5144 series of high-speed operational amplifiers. It is designed for video and broadband applications where fast transient response is critical. The CMOS construction allows for efficient power usage compared to bipolar alternatives. The series is known for combining speed with compact packaging options.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes. Verify that any alternative maintains the 200 V/µs slew rate and 60 MHz bandwidth. Ensure the replacement supports the same 5V supply voltage and SOT-23-5 package.
