Description: Outline
DMX512AP is parallel application of single-wire transmission control three-channel LED driver output dedicated chip, compatible and extended signaling protocol DMX512 (1990). The chip incorporates power regulator circuit, time base circuit, signal decoding module, data buffer, three-channel constant-current drive (current value by plug resistors regulation), as well as built-in oscillator. Each output channel can output 8-bit (256) grayscale adjustable linear current. Support the output polarity reversal. The The separate write code signal line can be a one-time series written code, with external EEPROM storage chip address support combination of DMX512A-W.
Feature Description
◆ three-channel open-drain output, the maximum constant current output: 60mA
◆ output port withstand voltage 24V
◆ Operating voltage: 4V ~ 24V
◆ Built-in 5V regulator circuit
◆ signal transfer rate: 250kbps (PWM version) to 500kbps (PFM version)
