LMH6572MQX

Analog Switches - Special Purpose Overview

The LMH6572MQX is a triple 2:1 high-speed video multiplexer in a 16-pin SSOP package. It features a 350 MHz small-signal bandwidth and a 290 MHz large-signal bandwidth at 2 Vpp output levels. The device provides a fixed internal voltage gain of two, delivering an 80 mA linear output current capability. Key performance metrics include a 1400 V/µs slew rate, 10 ns channel switching time, and 90 dB channel-to-channel isolation at 5 MHz. Operating specifications support supply voltages from ±3V to ±6V with an operating temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm transport media and packaging configuration. Confirm that the component meets all required environmental and electrical specifications for the target application before integration. Ensure compatibility with existing logic thresholds for select and enable pins.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring high bandwidth and low distortion in video signal routing. Consider the fixed gain of two when designing circuit topology, particularly for back-terminated loads. Evaluate thermal dissipation requirements due to the quiescent current consumption within the SSOP package constraints.
