8-digit LED Driver
|
| |
Description:
The MAX7219 drives common-cathode LED displays from one to eight seven-segment digits in length. It can also be used to drive up to 64 discrete LEDs configured as eight common-cathode clusters of eight LEDs each. When the MAX7219 is used with seven-segment displays, it can be configured to automatically convert binary-coded decimal (BCD) values into appropriate patterns of segments. Built-in pulse-width modulation and current-limiting circuits control the brightness of the displays with only a single external resistor. With eight display digits, the MAX7219 scans the display at approximately 1200 Hz to prevent visible flicker of the display. If a display of less than eight digits is used, the driver can be programmed to scan only the digits actually connected to it, increasing the potential brightness and scanning frequency of the display.
