MAXIM INTEGRATED / ANALOG DEVICES MAX328EWE Ultra-Low Leakage Analog Multiplexer

The MAX328EWE is an ultra-low leakage, monolithic CMOS analog multiplexer in a 16-pin WSOIC package. It is a single-ended 8-channel multiplexer designed to minimize leakage currents, making it suitable for high-impedance sources such as op-amps and A/D converters. By adding an external 40 kΩ resistor to each input, the device becomes fault-tolerant, capable of withstanding 110V AC faults indefinitely while maintaining low error levels. The MAX328 operates with a single supply voltage from 10V to 30V or dual supplies from ±5V to ±18V, and performs reliably with unbalanced power supply configurations such as +12V and -5V or +5V and -15V. It features bidirectional operation, making it usable as a multiplexer or demultiplexer, with a typical switching speed of less than 1.5 microseconds. The device supports a wide temperature range from -40°C to 85°C, is compatible with TTL and CMOS logic levels, and includes latch-up proof construction. Its low power dissipation is approximately 1.9mW at ±15V supplies, with charge injection of 5pC at VA = 0V. Suitable for applications in control systems, data logging, aircraft heads-up displays, data acquisition, and signal routing.
