KM4200IM8TR3

Overview

The KM4200IM8TR3 is a dual, low-cost voltage feedback amplifier manufactured by Fairchild Semiconductor. It operates on +2.7V, +5V, or ±2.5V supplies with a bandwidth of 260MHz and a slew rate of 145V/µs. The device draws 4.2mA supply current per amplifier and provides ±55mA linear output current. It features rail-to-rail output capability, extending from 0.036V to 4.953V at Vs = +5V with a 2kΩ load. Input voltage ranges from -0.3V to +3.8V under the same conditions. The component is housed in an 8-SOIC (0.154", 3.90mm Width) package.

Procurement Notes

Verify the manufacturer part number KM4200IM8TR3 against official Fairchild Semiconductor documentation to confirm specifications. Ensure the 8-SOIC package type matches the design requirements. Cross-reference the datasheet for electrical characteristics such as bandwidth and supply voltage limits. Confirm that the component status is active before procurement. Validate compatibility with existing circuit designs regarding input/output voltage ranges.

Selection Notes

Select this component for applications requiring high-speed signal processing with low power consumption. The dual configuration allows for cost-effective implementation of differential or multi-channel systems. Consider the rail-to-rail output feature for maximizing signal integrity in low-voltage environments. Ensure the operating temperature range meets the system requirements. Verify that the 260MHz bandwidth is sufficient for the intended signal frequencies.

Part Context

The KM4200 series includes single and dual amplifier variants, such as the KM4100 and KM4101. These devices are designed as low-cost alternatives to higher-performance amplifiers like the AD8052 and AD8042 in single-supply applications. The series offers various package options including SOIC and MSOP to suit different board space constraints.

Replacement Considerations

The datasheet indicates direct replacement for AD8052 and AD8042 in single-supply applications. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure that the replacement component meets the specific bandwidth and slew rate requirements of the original design.
