Maxim Integrated MAX4571CEI-T Low-Voltage, CMOS Analog Multiplexers/Switches

The MAX4571CEI-T is a high-performance, low-voltage dual 4-channel CMOS analog multiplexer/switch from Maxim Integrated, designed to provide precision signal routing in a variety of applications. This device is particularly well-suited for battery-operated equipment due to its low power consumption and wide single-supply voltage range of 1.8V to 5.5V or dual supplies of ±2.5V. The MAX4571CEI-T is available in a compact 16-pin QSOP package, making it an excellent choice for space-constrained applications.

Featuring low on-resistance (100 ohms max) and flatness (4 ohms max), the MAX4571CEI-T ensures signal integrity is maintained across its channels, which is essential for maintaining the fidelity of the analog signals being switched. On-resistance matching between channels is less than 2.5 ohms, and the on-resistance is quite linear over the input signal range, which results in minimal signal distortion.

The device's digital logic inputs are TTL and CMOS compatible, allowing for easy interfacing with a wide range of control logic. Additionally, the MAX4571CEI-T offers low crosstalk and off-isolation parameters, which are critical for reducing signal interference in multiplexing applications. This makes the device an excellent choice for use in data acquisition systems, communication systems, audio signal routing, and other applications where multiple analog signals need to be routed with high precision and minimal interference.

For enhanced reliability, the MAX4571CEI-T features built-in charge pump circuitry, which eliminates the need for external voltage supplies to drive the analog switches. This integrated charge pump ensures that the analog switch can pass signal levels that include both ground and the positive supply rail, a feature known as "rail-to-rail" operation. Furthermore, the device has ESD protection of ±2kV, which helps to safeguard against damage from electrostatic discharge events.

Overall, the MAX4571CEI-T from Maxim Integrated is a robust and versatile solution for designers looking for a reliable, low-voltage analog multiplexer/switch that offers high performance in a small package.
