KM4101IC8TR3

Overview

The KM4101IC8TR3 is a single-channel, low-cost voltage feedback operational amplifier manufactured by Fairchild Semiconductor. It features a bandwidth of 260 MHz and a slew rate of 150 V/µs. The device operates on supply voltages of +2.7V, +5V, or ±2.5V. Key electrical parameters include a supply current of 4.2 mA and a linear output current capability of ±60 mA. The input voltage range extends from -0.3V to +3.8V at a +5V supply. It supports direct replacement for AD8051 and LM7131 in single-supply applications.

Feature Summary

• Ultra-fast signal processing with 260 MHz bandwidth and 150 V/µs slew rate
• Low power consumption with 4.2 mA supply current and power-down mode
• Wide operating voltage range supporting +2.7V, +5V, and ±2.5V supplies
• High drive capability with ±60 mA linear output current

Applications

• A/D driver circuits
• Active filters
• CCD imaging systems
• Video drivers
• Coaxial cable drivers

Procurement Notes

Verify the specific suffix IC8TR3 corresponds to the SOIC-8 tape and reel packaging configuration. Confirm that the component is sourced from Fairchild Semiconductor or its authorized successor entities to ensure authenticity. Check for RoHS compliance status as specifications may vary by production batch. Ensure the operating temperature range matches the application requirements before procurement.

Selection Notes

Select this component when high-speed signal amplification is required within a low-power constraint. It is suitable for designs needing rail-to-rail output swing near the negative supply rail. Consider the SOIC-8 package for standard surface-mount assembly. Evaluate thermal dissipation capabilities given the 4.2 mA quiescent current. Verify compatibility with existing single-supply architectures replacing legacy parts like the AD8051.

Part Context

The KM4101 is part of the KM4100 series of low-cost, high-speed amplifiers. It shares the same core performance characteristics as the KM4100 but includes an additional disable pin for power management. This variant allows for system-level power savings through software control. The series is designed for portable and battery-powered applications requiring efficient energy usage without sacrificing speed.

Replacement Considerations

The datasheet explicitly states that the KM4100/KM4101 series directly replaces the AD8051 and LM7131 in single-supply applications. Designers should verify pinout compatibility and ensure that the disabled state of the KM4101 meets the circuit's leakage requirements when replacing these legacy amplifiers.
