The LM3915 is a monolytthic IC designed to sense analogue voltage signals, and produce an incremental or sequential logic switching across its 10 output. 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.

2019年4月20日 · The LM3915 is a Logarithmic Display Driver IC commonly used in visualizing audio signals. It can drive both 10-segment Bar LED and Dot Matrix LED. The IC also allows the reference voltage and LED current to be easily programmed based on the application by selecting the right value of resistors.
