KM4110IT5TR3

Overview

The KM4110IT5TR3 is a single ultra-low power, low cost voltage feedback amplifier manufactured by Fairchild Semiconductor. It operates on +2.7V or +5V supplies with a supply current of 0.5mA. The device features a 75MHz small signal bandwidth and a 20V/µs slew rate. Input voltage range extends below the negative rail, while output swings near the rails. It is designed for battery-powered communication and computing systems.

Feature Summary

Ultra-low power consumption suitable for portable applications
High bandwidth and fast slew rate for signal integrity
Rail-to-rail input and output performance
Low cost design replacing legacy amplifiers

Applications

Portable and battery-powered devices
Analog-to-digital converter buffers
Active filter circuits
Signal conditioning stages
Portable test instruments

Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor, noting its acquisition history. Confirm the specific suffix IT5TR3 indicates the tape and reel packaging format and temperature grade. Ensure the component matches the original Fairchild specifications rather than subsequent rebranding variations.

Selection Notes

Select this amplifier when low power consumption is critical alongside high bandwidth requirements. It serves as a direct replacement for the MAX4281 in existing designs. Consider the SOT23-5 package for space-constrained PCB layouts. Evaluate the input offset voltage and noise specifications against system sensitivity needs.

Part Context

This component belongs to the KM411x series of rail-to-rail amplifiers. The KM4110 variant offers higher bandwidth compared to the KM4111. The series is characterized by combining bipolar performance metrics with CMOS pricing advantages. It targets applications requiring efficient power usage without sacrificing signal speed.

Replacement Considerations

The datasheet explicitly states it directly replaces the MAX4281. Verify pinout compatibility before substitution. Check if alternative packages like SOT23-6 are required for disable functionality found in other series members.
