MAX385ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX385ESE+ is a precision, low-voltage analog switch featuring two double-pole single-throw (DPST) channels in a 16-pin Narrow SOIC package. It operates with a single positive supply from +3V to +15V or split supplies of ±3V to ±8V. The device provides an on-resistance of less than 35Ω, guaranteed to match within 2Ω between channels and remain flat over the specified analog signal range with a maximum variation of 4Ω. Key electrical characteristics include a turn-on time of less than 175ns, a turn-off time of less than 100ns, and charge injection of less than 5pC. Leakage current is specified at less than 250pA at +25°C and less than 2.5nA at +85°C.
