MAX7219 MAX7219CWG MAX7219EWG SOP24 LED Display Drivers

The MAX7219 is an integrated circuit designed for controlling 8-digit 7-segment LED displays, as well as bar graph and dot matrix displays. It reduces the complexity of driving these displays by managing the multiplexing and segment current control, which in turn minimizes the number of microcontroller I/O pins required. The IC is available in a SOP-24 SMD package, making it suitable for compact and space-efficient designs.

Features:

• Drives 8-Digit LED Displays: Capable of controlling up to 8 digits of 7-segment displays or 64 individual LEDs, with minimal external components.
• SPI-Compatible Interface: Uses a simple Serial Peripheral Interface (SPI) for communication, reducing the number of microcontroller I/O pins needed.
• Built-in BCD Decoder: Includes a BCD (Binary Coded Decimal) decoder for direct interfacing with numeric displays.
• Adjustable Brightness: Features digital control of display brightness, allowing for adjustment via software.
• Low Power Shutdown Mode: Provides a low-power shutdown mode to conserve energy when the display is not in use.
• SOP-24 SMD Package: Compact surface-mount package, ideal for high-density PCB designs.

Package Includes:

• 1 x MAX7219 – 8-Digit LED Display Driver IC – SOP-24 SMD
