MAXIM MAX391 MAX392 MAX393 Precision, Quad, SPST Analog Switches Product Data Sheet Manual User Guide
Summary
These precision quad SPST analog switches (MAX391/MAX392/MAX393) are industry-leading components designed for applications requiring reliable, low-current signal switching. They offer ultra-low on-resistance, extremely low power consumption (< 1µW), and fast switching speeds while guaranteeing excellent channel matching across various single and bipolar supply voltages (+3V to +15V). The comprehensive manual provides detailed operational specifications, package information (DIP, SO, TSSOP, QFN), truth tables, and application guidance for engineers in military radios, test equipment, battery-powered systems, and communications networking.
