• RE: LTC2945 Sampling time

    Greetings Cyril,

       Thank you for your interest in the LTC2945.  The sampling rate of the ΔΣ ADC is approximately 30.7kHz.  Given the noisy environment in which you plan on using the part, a single-pole RCR filter with R= 10Ω and C=2.2uF would…

  • LTC2945 Start-up

    Hello, I have a question about the LTC2945.
    My customer is considering the LTC2945.
    I received a question from a customer.

    How many mS after power-up is desired when the microcontroller accesses the LTC2945 via I2C?
    Or should the microcontroller retry until…

  • LTC2945 communication problem


    My schematic is simple as shown in datasheet:

    The ADIN is grounded as not used. 

    ADR1 and ADR0 are connected to ground. So, device address should be 0xDE.

    However I dont get any ACK when shifting address as below:

    Any idea would be welcomed…

  • LTC2946/LTC2945

    My application is to use the LTC 2946 in a serial connected string of batteries to measure total string current and voltage appliyng it in two distinct design:
    One for -48V as commoly used in telecom industry, and another one to be used to read from +4…

  • LTC2945 communicate problem in reading

    My schematic is simple as shown in datasheet, the VDD and INTVCC is powered by 3.3V.

    The master communicated with the slave by using the common Mass Writeaddress (1100 110b).
    When I read the REGISTER ADDRESS(02h) as figure 10, after the S(start), the…
