MAX388EPN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX388EPN is a single-channel, high-voltage analog multiplexer manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features an 8:1 switching configuration housed in an 18-pin PDIP package. The device operates on dual supplies ranging from ±4.5V to ±18V or a single supply up to 36V. Key electrical parameters include a maximum on-resistance of 3kΩ, a channel-to-channel matching of 300Ω, and a typical charge injection of 55pC. Switching times are specified at 1.5µs for turn-on and 1µs for turn-off. The component supports a leakage current of 500pA and functions within a commercial temperature range of 0°C to 70°C.
