Linear Technology LTC1391CS Multiplexer

The LTC1391CS is a versatile and high-performance multiplexer from Linear Technology, now part of Analog Devices, designed for precision data acquisition systems and signal routing applications. This integrated circuit is capable of multiplexing eight single-ended inputs or four differential inputs to a single output, providing users with a compact solution for channel selection in complex systems.

One of the key features of the LTC1391CS is its low on-resistance of typically 125 ohms, which minimizes signal attenuation and ensures the integrity of the signal being passed through the multiplexer. Additionally, the on-resistance is matched between channels to within 6 ohms and remains flat over the entire analog signal range, which is essential for maintaining signal fidelity and reducing distortion in precision applications.

The LTC1391CS operates from a single 5V supply, making it compatible with a wide range of systems and simplifying power supply design. It also offers a low power shutdown mode, reducing power consumption when the multiplexer is not in active use, which is particularly beneficial for battery-operated and power-sensitive designs.

The device is controlled via a 3-wire serial interface, which enables the selection of the desired channel using a minimal number of control lines, thereby saving valuable board space and reducing the complexity of the system's interconnections. This serial interface is CMOS and TTL compatible, ensuring easy integration with a variety of microcontrollers and digital systems.

The LTC1391CS comes in a compact 16-pin narrow SO package, allowing for a reduced footprint on printed circuit boards. Whether used in data acquisition systems, process controls, or automated test equipment, the LTC1391CS is a reliable choice for designers looking for a high-quality multiplexer with excellent performance characteristics.

Overall, the LTC1391CS is a testament to Linear Technology's commitment to providing innovative, high-performance integrated circuits that meet the demanding requirements of modern electronic systems.
