The LTC1390CS#PBF is a high-performance, 8-channel analog multiplexer from Linear Technology, now part of Analog Devices. This device is designed to facilitate the efficient routing of analog signals in electronic systems, making it an invaluable component for a wide range of applications including data acquisition systems, test equipment, and signal processing circuits.

Key Features

• 8-Channel Multiplexer: The LTC1390CS#PBF can connect one of eight inputs to a common output, allowing for versatile signal management within a circuit.
• Single Supply Operation: This multiplexer operates from a single 5V supply, simplifying the power design requirements for the system it's integrated into.
• Low On Resistance: The on resistance is typically 125 ohms, which ensures minimal signal attenuation and distortion when the switch is closed.
• Low Crosstalk: The device exhibits low crosstalk between channels, which is critical for maintaining signal integrity in high-precision applications.
• Serial Interface: The LTC1390CS#PBF features a serial interface that allows for easy control via a microcontroller or processor and reduces the number of GPIO pins needed for operation.
• Break-Before-Make Switching: This feature ensures that no two channels are connected simultaneously, preventing signal interference and shorting during channel switching.
• Wide Operating Temperature Range: The device is rated for operation over the industrial temperature range of -40°C to 85°C, making it suitable for harsh environments.
