The LM3914N-1/NOPB is a versatile LED bar graph/LED dot display driver integrated circuit (IC) produced by Texas Instruments. This device is designed to drive a series of LEDs in either a bar graph or dot mode, making it ideal for visual representation of analog signals, such as voltage levels or audio signals.
Key Features:
-
Display Modes: The LM3914 can operate in two modes:
- Bar Graph Mode: In this mode, the LEDs light up in a linear fashion, providing a visual representation of the input signal level.
- Dot Mode: In this mode, only one LED is lit at a time, indicating the current level of the input signal.
-
Input Voltage Range: The IC can accept an input voltage range from 0V to 1.2V, allowing it to be used with a variety of signal levels.
-
LED Drive Capability: The LM3914 can drive up to 10 LEDs in series, with a maximum output current of 30 mA per LED. This makes it suitable for driving standard 20 mA LEDs.
-
Temperature Range: The device operates over a wide temperature range, typically from -40°C to +85°C, making it suitable for industrial applications.
-
Power Supply: The LM3914 operates on a single supply voltage, typically between 3V and 25V, which provides flexibility in various circuit designs.
-
Pin Configuration: The IC is available in a 10-pin DIP (Dual In-line Package) or surface mount package, facilitating easy integration into different circuit layouts.
-
Internal Reference: The LM3914 includes an internal reference voltage, which can be used to set the scale of the display, allowing for easy calibration and adjustment.
-
Ease of Use: The device is designed for straightforward implementation, requiring minimal external components. This makes it an excellent choice for hobbyists and professionals alike.
