Maxim Integrated MAX4547CSE+ Low-Voltage, Single-Supply Multiplexer

The Maxim Integrated MAX4547CSE+ is a versatile and high-performance analog multiplexer that operates with a single supply voltage ranging from 2.7V to 12V, or dual supplies of ±2.7V to ±6V. This makes it an ideal choice for battery-powered and portable applications where power efficiency is crucial.

Featuring a 4-channel, single-ended signal configuration, the MAX4547CSE+ provides a flexible solution for routing analog signals in a variety of systems. Its low on-resistance (100 ohms max) and on-resistance matching between channels (6 ohms max) ensure signal integrity, while its low leakage currents (2nA max at +25°C) minimize power consumption and increase accuracy in sensitive applications.

The MAX4547CSE+ is designed to handle rail-to-rail analog signals, making it highly compatible with modern low-voltage digital systems. This capability allows the multiplexer to pass signals from ground to the supply rail without distortion or attenuation, a feature that is particularly important in audio, data acquisition, and communication systems.

Control of the MAX4547CSE+ is achieved through a digital interface, which uses TTL/CMOS logic levels for compatibility with a wide range of microcontrollers and digital systems. The Break-Before-Make feature ensures that no two channels are connected simultaneously, preventing signal crosstalk and ensuring smooth transitions between channels.

Encased in a 16-pin narrow SO package, the MAX4547CSE+ is designed for space-saving in PCB designs, without compromising on performance. Its extended temperature range of -40°C to +85°C allows for operation in harsh environments, making it suitable for industrial and automotive applications as well.

With its combination of low-voltage operation, precision signal handling, and digital control, the MAX4547CSE+ from Maxim Integrated is a reliable and efficient choice for multiplexing analog signals in a wide range of electronic systems.
