LMH6560 - Closed-Loop Buffer

Datasheet Summary

Description

The LMH™6560 is a high speed, closed-loop buffer designed for applications requiring the processing of very high frequency signals.

While offering a small signal bandwidth of 680MHz, and a very high slew rate of 3100V/µs the LMH6560 consumes only 46mA of quiescent current for all four buffers.

LMH6560 Quad, High-Speed, Closed-Loop Buffer December 2004 LMH6560 Quad, High-Speed, Closed-Loop Buffer General Description The LMH™6560 is a high speed, closed-loop buffer designed for applications requiring the processing of very high frequency signals. While offering a small signal bandwidth of 680MHz, and a very high slew rate of 3100V/µs the LMH6560 consumes only 46mA of quiescent current for all four buffers. Total harmonic distortion into a load of 100Ω at 20MHz is −51dBc. The LMH6560 is configured internally for a loop gain of one. Input resistance is 100kΩ and output resistance is but 1.5Ω. Crosstalk between the buffers is only −55dB. These characteristics make the LMH6560 an ideal choice for the distribution of high frequency signals on printed circuit boards.
