LMH6560MTX/NOPB

Overview

The LMH6560MTX/NOPB is a quad, high-speed closed-loop buffer designed for processing very high frequency signals. It features a small signal bandwidth of 680MHz and a slew rate of 3100V/µs while consuming only 46mA of quiescent current across all four buffers. The device offers low output resistance of 1.5Ω, input resistance of 100kΩ, and crosstalk of -55dB. Differential gain and phase are specified at 0.10% and 0.03° respectively at 3.58MHz. It supports single supply operation with a minimum voltage of 3V.

Feature Summary

• Quad configuration providing four independent high-speed closed-loop buffers within a single package
• High-frequency performance capability with 680MHz small signal bandwidth and 3100V/µs slew rate
• Low distortion characteristics including -51dBc total harmonic distortion at 20MHz into a 100Ω load
• Video signal buffering suitability with precise differential gain and phase specifications

Applications

• Multi-channel video distribution systems
• Video switching and routing infrastructure
• High-speed analog multiplexing circuits
• Channelized electronic warfare (EW) applications
• Broadcast and high definition TV systems

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel transport media associated with the MTX designation. Ensure compatibility with the 14-pin TSSOP package dimensions for PCB layout. Confirm that the application environment remains within the specified operating temperature range of -40°C to +85°C. Validate power supply requirements against the single-supply minimum of 3V or dual-supply configurations up to 10V per rail.

Selection Notes

Select this component when driving multiple transmission lines or distributing high-frequency signals with minimal crosstalk. The internal loop gain of one simplifies circuit design by eliminating external feedback components. Consider the 80mA output current capability for driving low impedance loads directly. Evaluate thermal dissipation requirements based on the 14-pin TSSOP package thermal resistance if operating near maximum ambient temperatures.

Part Context

This device belongs to the LMH6560 family of high-speed amplifiers manufactured using VIP10 process technology. It serves as a specialized buffer solution distinct from general-purpose operational amplifiers due to its optimized closed-loop architecture. The component addresses the need for signal integrity in high-density buffering scenarios where propagation delay and frequency response are critical constraints.

Replacement Considerations

Direct substitutes include other quad high-speed buffers from the same manufacturer family. Verify pinout compatibility and electrical specifications such as bandwidth and slew rate before substitution. Check for equivalent packaging options if the original MTX variant is unavailable.
