MAX391EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX391EUE+ is a quad single-pole single-throw (SPST) normally closed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 3V to 15V or dual supplies of ±3V to ±8V. The device features a maximum on-resistance of 35 Ohms and a channel-to-channel matching of 300 milliohms. Key electrical parameters include a maximum on-time of 130ns, off-time of 75ns, charge injection of 2pC, and leakage current of 100pA. It provides -85dB crosstalk at 1MHz and is housed in a 16-pin TSSOP package with an operating temperature range of -40°C to +85°C.
