MAX385EPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX385EPE+ is a precision, low-voltage analog switch featuring two double-pole single-throw (DPST) channels in a 16-pin Plastic DIP package. It operates with a single positive supply from +3V to +15V or split supplies from ±3V to ±8V. The device offers a maximum on-resistance of 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 parameters include a maximum turn-on time of 175ns, a maximum turn-off time of 100ns, and charge injection less than 5pC. Leakage current is specified at less than 250pA at +25°C and less than 2.5nA at +85°C. Power consumption is under 10µW.
