LED顯示屏驅動芯片

TM1819是為LED顯示面板設計的專用驅動IC，它內建的CMOS位移寄存器與鎖存功能，可以將串行的輸入數(shù)據(jù)轉換成平行輸出數(shù)據(jù)格式。TM1819具有16個電流源，可以在每個OUT輸出端口提供固定恒流來驅動LED；且當電壓發(fā)生波動時,對其輸出電流影響很小，能有效提高LED壽命和發(fā)光穩(wěn)定性。 ? 16 個恒流源輸出通道\n\n? OUT端口耐壓7.0V\n\n? 電流輸出大小不因輸出端負載電壓變化而變化\n\n? 恒流電流值，38.0mA@VDD=5.0V\n\n? 精確的電流輸出值，通道間誤差：≤±2.5％，芯片間誤差：≤±3.0％\n\n? 高達 25MHz 時鐘頻率\n\n? 工作電壓：3.0V～5.5Ｖ\n\n? 封裝形式：SSOP24、QSOP24;
