MAX391CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX391CPE+ is a precision, quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3V to 15V supply or dual ±1.5V to ±7.5V supplies. The device features a maximum on-resistance of 35 Ohms and supports a continuous DC switch current of 30 mA. Electrical performance includes a maximum turn-on time of 130 ns and a maximum turn-off time of 75 ns. Power dissipation is rated at 696 mW with a maximum supply current of 1 uA. It is housed in a 16-pin SOIC-Narrow package and functions within an operating temperature range of 0°C to +70°C.
