• SPI Communication issue with LTC2494

    For Data Input register(on SDI pin), it requires data should be clocked on rising edge and for Output Data Register(on SDO pin) data should be clocked on falling edge .

    but in STM32 we can't change the CPHA  & CPOL of SPI (phase and Polarity ) in Between…

  • In LTC2494- difficulty in data read-back

    We have set the channel  as per the channel selection table no 3 & 4.

    For Channel no 12, we passed data on SDI 1011 0110 1000 0000 1111 1111 (last 8 bits are dummy).

    Then we read-back data on SDO line by sending dummy data (same as channel no.12 selection…

  • LTC2494 / 95 differential input configuration

    I2C serial ADC LTC2494 / LTC2495.

    I am making 8x differential measurements via resistor divider of inputs that are connected in series, I will need to connect together inputs 14-13, 12-11, 10-9, 8-7, 6-5, 4-3, 2-1 (reference to Table 3 of datasheet)…

  • LTC2494 SPI Communication Issue/garbage result at SDO

    We are using LTC2494 with STM32 . we have Initialized SPI for channel No 14 with gain = 1 in single ended mode 

    we have set input Data register with value of 47024 (in decimal) ,

    we have not given any analog voltage to Channel no 14, even also we got  some…
