Maxim Integrated MAX4730EXT+T Analog Multiplexer

The MAX4730EXT+T from Maxim Integrated is a high-performance, low-voltage, 4:1 analog multiplexer that comes in a tiny, surface-mount, 6-pin SC70 package. This component is designed for precision signal routing in applications where space is at a premium and low power consumption is essential.

With single-supply operation ranging from +1.6V to +3.6V, the MAX4730EXT+T is perfect for portable and battery-powered devices. It boasts a low on-resistance of 100Ω (max) matched between channels to within 4Ω and flat (0.8Ω max) over the specified signal range. This ensures minimal signal distortion and provides excellent performance for routing audio or video signals, as well as other analog data.

The device's on-resistance is also matched over the full operating temperature range of -40°C to +85°C, ensuring consistent performance in a wide variety of environmental conditions. The MAX4730EXT+T features fast switching speeds (t<sub>ON = 30ns and t<sub>OFF = 20ns), making it suitable for high-speed applications.

Furthermore, the MAX4730EXT+T offers a low leakage current (0.1nA at +25°C) and low power consumption, which is critical for extending battery life in portable applications. Its high off-isolation of -75dB at 1MHz helps to prevent signal crosstalk, which is particularly important in multiplexed signal environments.

Designed with a break-before-make switching action, the MAX4730EXT+T prevents momentary shorting when switching channels. This feature is crucial for protecting sensitive analog circuits and preserving signal integrity. The device is also TTL/CMOS logic compatible, allowing easy integration with digital controllers and processors.

In summary, the Maxim Integrated MAX4730EXT+T analog multiplexer is an ideal solution for designers looking for a compact, efficient, and reliable way to route multiple analog signals in their applications. Whether used in medical equipment, communication devices, or consumer electronics, the MAX4730EXT+T combines high performance with the practical benefits of a miniature package.
