 Slkor LM393: A Cost-Effective Alternative to TI LM393DR and ONSEMI LM393DR2G V cc ：±18~36V V IO ：±3mV I IB ：25nA V I ：-0.3~36V T RE ：1.3μs Package：SOP-8 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 ...
