MAX397CAI+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX397CAI+T is a dual, 8-channel low-voltage CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with single supplies from +2.7V to +16V or dual supplies of ±2.7V to ±8V. The device features a maximum on-resistance of 100Ω and guarantees an on-resistance matching between channels of 6Ω max. Input off-leakage current is less than 1nA at +85°C, while output off-leakage is under 2.5nA. It provides fast switching speeds with transition times under 250ns and includes electrostatic-discharge protection exceeding 2000V.
