MAX4581ASE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4581ASE is a low-voltage, CMOS analog multiplexer configured as an 8-channel to 1-channel switch. It operates with dual power supplies ranging from ±2V to ±6V or a single supply from +2V to +12V. The device handles rail-to-rail analog signals with an on-resistance of 80 ohms maximum and channel-to-channel matching of 1 ohm. Digital inputs feature 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. Key electrical parameters include a maximum off-leakage current of 1nA at +25°C, charge injection of 0.5pC, and crosstalk of -78dB at 1MHz. Switching times are specified with a maximum turn-on time of 200ns and turn-off time of 100ns.
