    ltc2440

    I've got 24bit ADC chip LTC2440 from Linear in 16 pin SSOP pckage. After reading the datasheet, i build the circuit with ATMEGA16 and SHIFTIN to get the data. But I got strange data and it's not represent the data expected?
    ANybody can gave me some advice?

    LTC 2440 Interfacing : Help!

    If you could put up the schematic, it would be easier to answer.

    chek the reference voltages, may be they are not correct

    This is the circuits. CS I held low (grounded), SDI I held high (VCC), So I need only to poll the SDO pin and wait it to go low

    according to the PDF, the reference voltage is from 0,1V - VCC so it doesn't makes a matter :D
