LM393N Comparator UNNIC 10pcs DIP-8 Low Voltage, 36V, 0.4mA Supply

Description

Product Overview

The UNNIC LM393N is a low‑voltage comparator designed for demanding industrial and scientific environments. Housed in a compact DIP‑8 package, this component operates reliably up to 36 V DC while drawing only 0.4 mA from the supply, making it exceptionally energy‑efficient. Its input bias current is limited to 200 µA, which reduces loading on preceding circuitry and improves overall system accuracy. Constructed from high‑grade copper leads and a robust silicon die, the LM393N offers excellent thermal conductivity and resistance to mechanical stress, ensuring consistent performance over a wide temperature range. The device features a single‑supply operation mode, allowing it to function with either AC or DC power sources, and it includes an internal pull‑up resistor that simplifies external circuit design. With a maximum operating frequency of several hundred kilohertz, the LM393N can handle fast signal transitions, making it suitable for pulse‑width modulation, zero‑cross detection, and other time‑critical applications. The part number 024409 identifies this specific configuration, and the package includes ten individual units, providing ample inventory for production runs or prototyping projects.

Usage

Engineers and system integrators frequently employ the LM393N in a variety of signal‑conditioning scenarios. In industrial automation, the comparator can monitor voltage levels from sensors such as proximity switches, temperature transducers, and pressure transducers, triggering alarms or control actions when thresholds are crossed. Its low input current makes it ideal for battery‑powered remote stations where power conservation is critical. In laboratory instrumentation, the LM393N serves as a precise reference for analog‑to‑digital conversion, providing clean, noise‑free switching signals that improve measurement fidelity. The DIP‑8 footprint aligns with standard breadboard and PCB layouts, allowing rapid prototyping and seamless integration into existing designs. Additionally, the component’s ability to operate from either AC or DC sources expands its applicability to mixed‑signal environments, such as motor control circuits where voltage fluctuations are common. Users can also employ the LM393N in educational settings to demonstrate fundamental comparator behavior, thanks to its clear pinout and straightforward operation mode.

FAQ

What is the maximum input voltage for the LM393N?

The comparator can handle input voltages up to the supply voltage, which is rated at 36 V DC. Exceeding this limit may damage the device.

Can the LM393N be used with a single power source?

Yes, the LM393N is designed for single‑supply operation, allowing it to function with either an AC or DC source without the need for dual‑rail power supplies.

Is the DIP‑8 package compatible with surface‑mount technology?

The standard LM393N is supplied in a through‑hole DIP‑8 format. For surface‑mount applications, UNNIC offers a compatible SMD version under a different part number.

How does the low input current benefit battery‑operated devices?

With an input bias current of only 200 µA, the comparator draws minimal power from the signal source, extending battery life and reducing the need for frequent recharging or replacement.
