• RE: LTC1804 with strange behavior

    I am going to assume you are referring to the LTC1408-12. The LT1804 is an op amp. If you look at the LTC1408-12 timing diagram on page 10 of the data sheet, it quite clearly states that SDO represents the analog input from the previous conversion at…

  • lower ADXRS620 output impedance , higher ADC accuracy ?

    Hi

    I use LTC1408 (ADC) to convert ADXL325 and ADXRS620 analog signals. LTC1408 ask to use a buffer amplifier before ADC to transform the analog signals, which have high source impedance.

    ADXL325 has an output impedance of 32k for LP filter, so it is…

  • RE: ADA4940 Model misbehaving.

    Harry, the circuits shown are only test circuits, to simplify the problem - not the full circuit. RL for the 4505's is approx 200k in the main design.

    The LTC1078 is used as a simple simulation of the front-end of the ADC, LTC1408, the give a load…
