LED driver IC (integrated circuit) that can drive up to 10 individual LEDs or LED bar graphs, with the brightness of each LED controlled by an analog input signal. The IC operates on a supply voltage range of 3V to 25V and can be used in a variety of applications, such as audio level meters, voltage level indicators, and VU meters.

The LM3914N-1 is a monolithic integrated circuit that includes a voltage reference, comparator, and an output stage consisting of a constant current source and 10 comparators. The IC can operate in dot mode or bar mode, which allows it to display an analog signal as either individual dots (LEDs) or a continuous bar graph.

The LM3914N-1 has a low quiescent current of 3.5mA, making it ideal for battery-powered applications. The IC also includes a built-in LED test feature that allows the user to verify the functionality of the LEDs and the IC itself.

The LM3914N-1 is available in a 18-pin DIP (dual in-line package) or SOIC (small outline integrated circuit) package and operates over a temperature range of -25°C to 85°C.
