• LTC2945 I2C max SCLK rate

    Hello ADI folks,

    I have a question regrading to the LTC2945 max SCLK rate.

    In the DS it is stated that max allowed SCLK is 400KHz, but it is under the Min column.

    Do you mean that 400KHz is the maximum guaranteed rate? Or 400KHz is the minimum rate to use…

  • Current Sensing with LTC2945

    Dear Sir I have questions about LTC2945. As the simplified schematic block shown in the data sheet, the delta-Vsense (current sensing) voltage is amplified by 20 and then is converted into digital bits which are stored in the register. The host MCU can…
