LTC1441CS8 Dual Comparator by Linear Technology

The LTC1441CS8 is a high-performance, dual comparator integrated circuit designed and manufactured by Linear Technology. This precision device is tailored for systems that require reliable and fast comparison of analog signals. The LTC1441CS8 is housed in a compact 8-pin SO package, making it suitable for space-constrained applications.

One of the key features of the LTC1441CS8 is its ultra-low power consumption, drawing typically only 4.5µA of supply current per comparator. This characteristic makes it an ideal choice for portable and battery-powered devices where power efficiency is critical. Additionally, the device operates from a single 2.5V to 11V supply or a dual ±1.25V to ±5.5V supply, providing flexibility in different power environments.

The LTC1441CS8 offers a tight input offset voltage of 5mV and an input bias current of 10nA, ensuring high accuracy in signal comparison. The comparators feature a fast propagation delay of 7µs, which enables rapid response times in applications that require quick decision-making capabilities, such as threshold detection and level shifting.

Another important aspect of the LTC1441CS8 is its built-in reference voltage of 1.182V, which eliminates the need for external precision references in many applications. This integrated reference is stable over temperature and supply variations, providing consistent performance throughout the operating range.

The device also includes a latch function that allows the output to be held until it is reset, which is useful in peak detection and sample-and-hold circuits. The push-pull CMOS outputs can drive up to 8mA, allowing the LTC1441CS8 to directly interface with a variety of digital logic levels without requiring additional buffer stages.

With its robust feature set, the LTC1441CS8 is well-suited for various applications including battery monitoring, window comparators, A/D converters, level translators, and voltage monitors. Its reliability and precision make it an essential component for engineers looking to design efficient and accurate electronic systems.

Linear Technology's commitment to quality ensures that the LTC1441CS8 meets the stringent requirements of industrial, automotive, and communication markets. As a result, designers can confidently incorporate this dual comparator into their circuits, knowing it will deliver consistent performance and durability.
