    Hi Janaranjana,

    You are going to have to look at the I/O voltages of both the TLC5540 and your controller.  If your controller can tolerate 5V input signals, you should not need any additional chips.  The TLC5540 falls under the 'high speed' ADC category so if you have additional questions, you can post them directly to the High-Speed Data Converter forum.

     

    Regards,

    Tom
