LTC1441CN8#PBF: Dual Comparator with 400mV Reference

The LTC1441CN8#PBF is a high-precision dual comparator manufactured by Linear Technology, designed to offer robust performance in a variety of applications. This integrated circuit (IC) features a built-in 400mV reference voltage, making it an excellent choice for systems that require precise voltage monitoring and control.

Housed in a narrow 8-pin DIP package, the LTC1441CN8#PBF is compact and suitable for space-constrained applications. Its small footprint does not compromise its functionality, as it contains two independent comparators, each with its own input and output. This allows for versatile configurations, including window comparators or dual threshold detectors.

The device operates with a single supply voltage ranging from 2.7V to 11V or a dual supply of ±1.35V to ±5.5V, providing flexibility in various power environments. Its low supply current of 10µA (typical) makes it an energy-efficient solution for battery-powered devices and portable equipment.

Each comparator of the LTC1441CN8#PBF has a separate input and output, with the outputs being push-pull types that can sink and source current. This feature enables direct interfacing with TTL or CMOS logic levels without requiring pull-up resistors, simplifying circuit design and reducing component count.

The IC boasts a fast response time with a typical propagation delay of 7µs, ensuring quick and reliable performance in time-sensitive applications. Additionally, the LTC1441CN8#PBF is equipped with a latch function, which allows the user to hold the comparator's output in a particular state, providing more control over the output signal.

With its built-in hysteresis, the LTC1441CN8#PBF offers enhanced noise immunity, ensuring stable operation even in electrically noisy environments. This makes it ideal for industrial control systems, voltage level monitoring, and other applications where precision and reliability are paramount.

In summary, the LTC1441CN8#PBF from Linear Technology is a versatile and reliable dual comparator that offers precise voltage detection, low power consumption, and compatibility with digital logic levels, making it a valuable component in a wide range of electronic systems.
