EL5133IW-T7A

Overview

The EL5133IW-T7A is a high-speed voltage feedback amplifier from the Intersil EL5132/EL5133 series, manufactured by Renesas Electronics Corporation. It features a 670MHz -3dB bandwidth and an ultra-low input noise voltage of 0.9nV/√Hz at 10kHz. The device operates on single supplies from 5V to 12V or dual supplies from ±2.5V to ±6V, drawing a typical supply current of 12mA. It provides a slew rate of up to 1000V/µs and maintains stability at gains as low as 10. The component is housed in a 5-lead SOT-23 package and is specified for operation over an ambient temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low voltage noise performance optimized for sensitive signal processing applications
• High-speed voltage feedback topology with exceptional slew rate and wide bandwidth
• Capable of driving low impedance loads with high output drive performance
• Operates efficiently with moderately low supply current consumption

Applications

• Pre-amplifier stages
• Receiver front-ends
• IF and baseband amplifiers
• ADC drivers
• DAC buffers

Procurement Notes

Verify that the ordering suffix 'T7A' corresponds to the specific tape and reel packaging configuration (7-inch tape, 250 pieces) documented in the official datasheet. Confirm the manufacturer designation aligns with Renesas Electronics Corporation, noting the historical Intersil origin of the product line. Ensure compliance with RoHS standards and Pb-free material sets as specified for this part number.

Selection Notes

Select the EL5133IW-T7A when a compact 5-lead SOT-23 footprint is required for high-frequency signal conditioning. This model is suitable for designs needing low noise and high slew rates without the disable pin functionality found in the EL5132 variant. Consider the thermal dissipation limits of the small package when operating at higher supply voltages or driving heavy loads.

Part Context

This component belongs to the EL5132/EL5133 family of ultra-low voltage noise, high-speed voltage feedback amplifiers. Originally developed by Intersil Americas Inc., the product line is now managed by Renesas Electronics Corporation. The EL5133 specifically offers the same electrical performance as the EL5132 but omits the chip enable/disable pin, resulting in a smaller 5-lead SOT-23 package compared to the 8-lead SOIC option.

Replacement Considerations

The EL5132ISW-T7A is a pin-compatible alternative within the same family, differing only by the inclusion of a Chip Enable (CE) pin and availability in an 8-lead SOIC package.
