MAX4581LEEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4581LEEE+ is a low-voltage CMOS analog multiplexer configured as an 8-channel switch. It operates from a single +2V to +12V supply and handles rail-to-rail analog signals. The device features TTL/CMOS-compatible digital inputs with logic thresholds of 0.8V to 2.0V. Key electrical parameters include a maximum on-resistance of 80Ω at +12V, a channel-to-channel on-resistance match of 4Ω, and off-leakage current of 2nA at +25°C. It is housed in a 16-pin QSOP package and supports an operating temperature range of -40°C to +85°C.
