Maxim Integrated MAX4772ETT+TG40 Precision Switch

The MAX4772ETT+TG40 is a high-performance, low-voltage, dual SPDT (Single Pole Double Throw) analog switch from Maxim Integrated. This precision switch is designed to operate from a single +1.8V to +5.5V power supply, making it an ideal choice for battery-powered and portable applications where power efficiency is crucial.

The MAX4772ETT+TG40 features a low on-resistance of just 0.6Ω (typical) at +5V, which minimizes signal distortion and ensures excellent signal integrity. This low on-resistance is matched between channels to within 0.05Ω (typical) and is flat (0.1Ω typical) over the specified signal range, offering consistent performance for both audio and data signals.

With its single-supply operation, this switch is not only energy-efficient but also simplifies design by eliminating the need for dual supplies. The MAX4772ETT+TG40 is capable of handling rail-to-rail analog signals, further enhancing its versatility in a wide range of applications, including signal routing, multiplexing, and battery-powered systems.

The switch's high off-isolation of -74dB at 1MHz and crosstalk of -85dB at 1MHz ensure minimal signal leakage and interference between channels, making it suitable for precision applications. The digital logic inputs are 1.8V CMOS compatible when using a single +5V supply, allowing for easy integration with modern microcontrollers and digital systems.

For added reliability, the MAX4772ETT+TG40 is specified over the extended -40°C to +85°C temperature range, ensuring consistent performance in harsh environments. The device comes in a compact 6-pin TDFN package with a thickness of just 0.8mm, which is perfect for space-constrained applications.

Overall, the MAX4772ETT+TG40 from Maxim Integrated is a robust and versatile switch that offers precision performance in a small footprint, making it an excellent choice for designers looking to optimize their systems for power and space without compromising on quality.
