The Typical Circuit Diagram of Monolithick Color Scanner (LM9832)

Published:2011/9/8 6:19:00 Author:Ariel Wang | Keyword: Typical , Monolithick, scanner | From:SeekIC

The circuit is constituted by the LM9832 typical single color scanner . RSENSE is the stepper motor current sense resistor. VT1 ~ VT4 are external drive tubes. LM9832 uses a USB interface.The data receives and sends through the D + and D-pins. These data is 3V differential signal. The circuit between LM9832 D + , D-pins-chip and the color scanner with a USB connector could be seen as the chart. R1 and R2 are two data lines limiting resistor. C1 and C2 are the capacitors to eliminate noise.R3 is the pull-up resistor , R4 is the pull-down resistor.
