MAX4623ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4623ESE is a dual, high-speed analog switch featuring two double-pole/single-throw (DPST) normally open channels. It operates from single positive supplies (+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 and flatness under 0.5Ω across the signal range. Leakage current remains below 500pA at +25°C and 5nA at +85°C. Switching times are fast, with turn-on under 250ns and turn-off under 200ns. It utilizes CMOS logic inputs and is housed in a 16-pin narrow SOIC package.
