MAX394EWP+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394EWP+ is a precision, low-voltage, quad single-pole/double-throw (SPDT) analog switch. It operates with bipolar supplies from ±2.7V to ±8V or a single supply of +2.7V to +15V. The device features an on-resistance of less than 35Ω at ±4.5V and guaranteed matching within 2Ω between channels. Turn-on time is typically 82ns and turn-off time is typically 57ns. Quiescent current is less than 1μA. Logic inputs are TTL and CMOS compatible. The component is housed in a 20-pin Wide SO package.
