LM393 Comparator 30pcs Dual Differential IC – Low Power DIP‑8 Todiys

Description

Product Overview

The LM393 Comparator series is a collection of 30 low‑power dual differential ICs housed in a compact DIP‑8 package. Each chip delivers high‑precision voltage comparison, making it ideal for a broad spectrum of industrial, scientific, and hobbyist projects. The device operates with a supply voltage range of 2 V to 36 V, providing flexibility across many power‑management and sensor‑interface designs. Its internal architecture features a low‑offset input stage, fast response time, and a robust output stage capable of sinking up to 16 mA, ensuring reliable operation even in noisy environments.

Physically, the IC measures 0.36 × 0.32 × 0.26 in and weighs only 0.35 oz, allowing designers to conserve board space while maintaining performance. The package is lead‑free and RoHS‑compliant, reflecting modern environmental standards. The LM393 is widely recognized for its stability, low quiescent current, and ability to operate over a wide temperature range, from –40 °C to 85 °C, which makes it suitable for both indoor and outdoor applications.

Usage

These comparators excel in power‑management circuits where precise voltage thresholds are required, such as battery monitoring, voltage regulators, and over‑current protection schemes. They are also perfect for sensor interfacing, including temperature, light, and pressure sensors, where the ability to detect minute voltage changes translates into accurate real‑world measurements. In industrial automation, the LM393 can be employed in signal‑conditioning modules, level‑detect circuits, and as part of larger analog‑to‑digital conversion systems.

Because of the low power consumption and small footprint, the LM393 is a favorite among hobbyists building Arduino or Raspberry Pi projects that need reliable analog comparison without draining the power supply. Its versatility also extends to educational labs, where students can experiment with comparator theory, hysteresis implementation, and open‑collector output behavior.

FAQ

What is the maximum input voltage range for the LM393?

The LM393 can handle input voltages up to the supply voltage, which ranges from 2 V to 36 V. This wide range allows it to be used in both low‑voltage battery‑powered circuits and higher‑voltage industrial systems.

Can the LM393 be used with open‑collector outputs?

Yes, the LM393 features an open‑collector output stage, meaning you can connect a pull‑up resistor to the desired voltage level. This configuration provides flexibility for interfacing with different logic families and voltage domains.

Is the DIP‑8 package suitable for surface‑mount applications?

The standard LM393 is supplied in a through‑hole DIP‑8 package, which is not intended for surface‑mount technology. For SMT designs, consider the LM393N or LM393M variants that are available in SOIC or MSOP packages.

How does temperature affect the comparator’s performance?

The LM393 operates reliably from –40 °C to 85 °C. Within this range, its offset voltage and response time remain stable, ensuring consistent performance in both indoor and outdoor environments.

What warranty does the product include?

All LM393 Comparator packs are covered by a 12‑month limited warranty against manufacturing defects. If you encounter any issues, contact our support team for a replacement or refund in accordance with our return policy.
