MAX388CWG

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX388CWG is a high-voltage analog multiplexer featuring an 8:1 configuration within a single circuit. It operates on dual supplies ranging from ±4.5V to ±18V and delivers a maximum on-resistance of 3kΩ with a channel-to-channel matching of 300Ω. The device supports switching times of up to 1.5µs for turn-on and 1µs for turn-off, while maintaining low charge injection at 55pC. Leakage current is limited to 500pA, and it functions within a commercial temperature range of 0°C to 70°C in a 24-SOIC package.
