Description

LM393 is an integrated circuit comprising two independent, high-precision voltage comparators, characterized by low offset voltage, with a maximum of 2.0mV. It is designed to operate over a wide voltage range with single-supply voltage, though it can also function with dual-supply voltage configurations. Moreover, it maintains low power consumption regardless of the supply voltage magnitude. One of its distinctive features is its ability to operate with a single-supply voltage, with the common-mode input voltage range of the comparators approaching ground level.

The main applications of the LM393 include limiters, simple analog-to-digital converters, pulse generators, square wave generators, delay generators, wideband voltage-controlled oscillators, MOS clock timers, multi-frequency oscillators, and high-level digital logic gate circuits. The LM393 is designed for direct connection to TTL and CMOS logic circuits. When powered by dual supplies, it is compatible with MOS logic circuits—highlighting a unique advantage of the low-power LM393 over standard comparators.


Features
● Wide single supply voltage range or dual supplies +2v to +36v or ±1v to ±18v

● Very low supply current (0.4ma) independent of supply voltage (1mw/comparator at +5v)

● Low input bias current: 25na typ

● Low input offset current: ±5na typ

● Input common-mode voltage range includes ground low output saturation voltage: 250mv typ. (io = 4ma) differential input voltage range equal to the supply voltage


Applications

● Zero-Crossing Detection

● Pulse Width Modulation (PWM)

● Overvoltage and Undervoltage Protection

● Analog-to-Digital Conversion (ADC)

● Window Comparators

● Oscillators

● Comparator-based Frequency Detectors

Recently, low-altitude economy has become a hot topic in the market. With the official implementation of the "Interim Regulations on the Management of Unmanned Aerial Vehicle Flights" at the beginning of the year and the inclusion of low-altitude economy in the government work report during the Two Sessions of 2024, the industry chain companies have quickly followed suit, ushering in many new developments. The low-altitude economy primarily refers to activities in the airspace below 1000 meters vertically, extending as needed to not more than 3000 meters, focusing on low-altitude flight activities with various manned or unmanned aerial vehicles. These activities, such as passenger and cargo transportation, serve as traction to drive the comprehensive economic format of vertical integration in related fields.   One of the core aspects of the low-altitude economy is eVTOL (electric Vertical Take-Off and Landing aircraft). Since the end of last year, several companies have been ...
