Overview
The MAX14756, MAX14757, and MAX14758 are quad single-pole single-throw (SPST) analog switches produced by Analog Devices Inc./Maxim Integrated. These devices are designed for low on-resistance and high performance in various analog signal routing and switching applications. They offer single-supply operation from +10V to +70V and bipolar-supply operation up to ±35V, making them versatile for a wide range of industrial, medical, and instrumentation applications.
