• LTC2947 Power measurement

    Dear Sirs,

    We have a customer which is evaluating LTC2947 in their desing of an audio power amplifier.

    Currently they face a problem while feeding a sine signal with 1kHz to 20 kHz frequency and measuring a power in continious mode.

    it seems that the…

  • Query for LTC2947 device ID

    Hi Analog team,  

    Any way to read the LTC2947 Device ID or HW ID or Manufacturer ID? If yes, what is the register and default value? ANy document stated this?

    Thanks.

    Regards,

  • about timing of shutdown of LTC2947

    I tried to get current value from spidevice with SpiDev.

    0x00 is obtained from 0x80 as fallowing:

    #####################

    spi=spi.spiDev()

    bytes = spi.xfer([0x01, 0x80, 1])

    print(bytes[2])

    #####################

    After I appled OVDD and AVCC/DVCC, it was confirmed…

  • LTC2927 Powersequencing

    In electrical characteristics section of the datasheet of the LTC2947, it is mensioned that the OVDD should be applied earlier or at the same time as AVCC/DVCC. In our application however the OVDD is generated from the Input supply we want to monitor…

  • RE: Regarding LTC2946 ,permits reverse current

    Hi Harish,

        The LTC2946 can only sense current flowing from Vin to Vout. It will not give a reading for currents flowing backwards. It will tolerate (will not sustain damage) reversed current as long as you do not exceed any of the voltages in the ABS…

  • RE: What are the min and max sample rates for the ADM1293-1 over temperature?

    Greetings,

       We do not spec for the minimum conversion time on this part and can offer no guarantees as to how fast it can possibly sample.  Based on how far apart the max value is from the typical value(~15%), you may be able to see conversions take place…

  • RE: LTC2946/LTC2945

    Greetings Anahia,

    Can we still reading the current converted by A/D and sampled as a positive number?

    If Sense- is above Sense+, the current ADC will give a reading of zero and no energy accumulation will occur.
