KM4101IT6TR3

Overview

The KM4101IT6TR3 is a single-channel, low-cost voltage feedback operational amplifier manufactured by Fairchild Semiconductor. It features a 260MHz bandwidth and operates on +2.7V, +5V, or ±2.5V supplies. The device includes an integrated disable function, allowing power-down current to reach 127µA. It offers a slew rate of 150V/µs, supply current of 4.2mA, and linear output current of ±60mA. The input voltage range extends from -0.3V to +3.8V at Vs = +5V.

Feature Summary

• Integrated disable pin for active power management
• Rail-to-rail output capability with wide supply voltage support
• High-speed performance suitable for demanding signal processing

Applications

• Analog-to-digital converter drivers
• Active filter circuits
• Video driver applications
• Portable and battery-powered equipment

Procurement Notes

Verify the specific suffix IT6TR3 against official Fairchild or ON Semiconductor documentation to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with the intended supply voltage range and disable logic requirements before procurement.

Selection Notes

Select this component when a disabled state is required to minimize quiescent current in portable designs. It serves as a direct replacement for AD8051 and LM7131 in single-supply configurations. Verify that the 4.2mA supply current meets system power budgets.

Part Context

This part belongs to the KM4100 series of rail-to-rail amplifiers. The '1' in KM4101 indicates the inclusion of a disable control feature, distinguishing it from the standard KM4100. It is designed for cost-sensitive applications requiring high bandwidth and low power consumption.

Replacement Considerations

Officially documented direct replacements include the AD8051 and LM7131 in single-supply applications. Verify pinout and electrical specifications match the original design constraints.
