[Other] DMX512APV3.1 DL : 1: 概述 DMX512AP是并联应用单线传输三通道LED驱动输出控制专用芯片，兼容并扩展DMX512（1990）信号协议。芯片内含电源稳压电路，时基电路，信号解码模块，数据缓存器,三通道恒流驱动器(电流值可由外挂电阻调控),以及内置振荡器。每一输出通道皆可输出8位(256级)灰阶的可调线性电流。支持输出端极性反转。单独的写码信号线可以一次性串联写码，带外置EEPROM存放芯片地址，支持与DMX512A-W组合使用。特性说明  ◆ 三通道开漏输出，最大恒流输出：60mA  ◆ 输出端口耐压24V  ◆ 工作电压：4V~24V  ◆ 内置5V 稳压电路  ◆ 信号传输速率：250kbps(PWM版本)~500kbps(PFM版本)  ◆ PWM 灰度等级：256 级  ◆ 外置EEPROM  ◆ 信号级联方式：单线并联  ◆ 最大支持1024 个像素点的串并接  ◆ 具有单通道/三通道选择功能  ◆ PWM 输出占空比反转功能  ◆ 兼容并扩展DMX512(1990)协议信号  ◆ 封装形式：SOP16 ◆ HBM ESD 达8KV 应用领域  ◆ 室内LED 装饰照明  ◆ 建筑LED 外观/情景照明  ◆ 洗墙灯、窗帘屏  ◆ 穿孔字  ◆ 护栏管 -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) &#
