MAX4623CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4623CSE+ is a dual, high-speed analog switch featuring two double-pole/single-throw (DPST) normally open channels. It operates from a single positive supply (+4.5V to +36V) or bipolar supplies (±4.5V to ±18V). The device guarantees an on-resistance of 5Ω maximum with a channel-to-channel match within 0.5Ω. Key electrical parameters include a turn-on time of 250ns maximum, a turn-off time of 200ns maximum, and off-leakage current below 5nA at +85°C. It utilizes a 16-pin Narrow SOIC package and supports TTL/CMOS logic inputs.
