The MAX6974ATL+ is a precision current-sinking, 24-output PWM LED driver from Analog Devices / Maxim Integrated. It is designed to drive red, green, and blue LEDs for full-color graphic message boards and video displays.
Each of the 24 outputs features individual 12-bit PWM intensity control for hue and 7-bit global PWM intensity control for luminance. The full-scale current for each bank of eight outputs is adjustable from 6mA to 30mA in 256 steps, allowing for color calibration. The device supports multiplexing to drive up to 48 LEDs.
Operating from a 3.0V to 3.6V logic supply and a 3V to 7V LED power supply, the MAX6974ATL+ requires only 0.8V headroom above the LEDs’ forward-voltage drop. It includes a high-speed, fully buffered, cascadable serial interface with differential signaling for improved signal integrity and reduced EMI. An optional watchdog timer can blank the display if signal inputs fail to toggle within 40ms.
The MAX6974ATL+ is available in a 40-pin TQFN package and operates over a temperature range of -40°C to +125°C. Its applications include LED video display panels, LED message boards, and variable message signs.
