MAX381CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX381CPE+ is a precision, low-voltage analog switch featuring a single-pole single-throw (SPST) configuration. It operates with a single positive supply ranging from +3V to +15V or split supplies of ±3V to ±8V. The device maintains 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. Leakage current is limited to less than 250pA at +25°C and 2.5nA at +85°C. Switching performance includes a turn-on time of less than 175ns and a turn-off time of less than 100ns. Charge injection is guaranteed to be under 5pC, and power consumption remains below 10µW.
