LMH6572MQ is a quad high-speed differential analog switch designed for applications in the frequency range from DC up to 6GHz. The device can be used to switch differential signals between different sources, reference signals, and power supplies. With its low insertion loss, excellent linearity and low crosstalk, it is ideal for applications such as high-speed differential data switches, test & measurement, robotic systems, and communications.

LMH6572MQ is a 16-pin TSSOP integrated circuit featuring four low-voltage, high-speed differential analog switches with an operating voltage range of 2.5V to 5.5V. The devices feature a low ON-resistance of 2.25 ohms maximum and a low propagation delay of 2.6ns maximum. The integrated circuit supports both single-ended switch configurations and differential-to-differential switch configurations for both positive and negative logic.

The LMH6572MQ is designed to be flexible in switch performance. It features a wide dynamic range, ensuring a low ON-state resistance over the entire supply voltage range. The device also has a low ON-resistance flatness of ≤ 0.8Ω, which ensures little or no signal attenuation at higher frequencies.

The device offers a high ON-state isolation of greater than 30dB and excellent crosstalk performance. It is capable of switching up to 4GHz differential signals with low crosstalk and excellent channel-to-channel isolation. With its high CMRR and low THD, the device can be used in a variety of high-fidelity applications.

The LMH6572MQ works by applying a logic-level control voltage to the input pins. A logic high voltage enables the switch to connect the input and output pins, allowing the signal to be transmitted. A logic low voltage will disconnect the connections and the signal is blocked. The output-enable pin is used to control the signal and can be used to send the signal from the input to the output independently.

The device is designed for use in robust automotive applications, industrial applications, consumer electronics, and communications systems. Its wide operating temperature range and low power mode makes it ideal for applications requiring a long lifetime. Additionally, the device meets AEC-Q100 safety standards, making it a reliable and robust option for use in automotive applications.

The LMH6572MQ is a versatile, reliable, and robust differential analog switch that provides high-speed switching, excellent linearity, low crosstalk, and low insertion loss. It is one of the best-performing devices currently available for switching differential signals between multiple sources. As a result, it is ideal for use in high-speed communications, test & measurement, robotic systems, automotive designs, and consumer electronics.
