Pengganti ic 7414/16/2023 The IC features an adaptable voltage reference and a precise 10 step voltage divider. The IC circuit including all the 10 LEDs can be operated using as low as 3V supply and upto 25V. The LED can be connected without limiting resistors since the IC includes internal programmable current regulation for the 10 outputs. The IC has one pinout for designating whether the output LEDs will sequence individually (dot mode) or in form of a bar graph. Inidicating devices likes LEDs, LCD or vaccum displays can be attached with these outputs to obtain a corresponding visual indication in response to the varying input analogue signal. The LM3915 is a monolytthic IC designed to sense analogue voltage signals, and produce an incremental or sequential logic switching across its 10 output.
