• My output DAC Voltage from LTC2644 Resets

    Dear Sir,

    LTC2644 Output Resets suddenly.While Switching ON some other systems.It Starts ramping LTC2644 DAC output voltage from 0V to Desired Voltage,But PWM input signal looks stable there is no Change in Duty Cycle of PWM Signal.I dont want to reset…

  • my output DAC Voltage from LTC2644 varying continuously

    i am using LTC2644 in motor control application. I am converting controlled PWM output to Analog Voltage by using LTC2644.But when feedback is connected to our system PWM Varies and Stabilize at one point,But my output DAC Voltage from LTC2644 varying…

  • LTC2644-L12 Rising Edge to DAC Update Delay

    Dear Sir,

    I'm using the LTC2644-12 for motor control applications.

    My PWM is set to 6kHz hence Tpwm=1/6000.

    I need some clarification about parameter t4 (device datasheet 2644fa), because  about t4 INA/INB Rising Edge to DAC Update Delay we can read…

  • LTC2644 Analog Voltage Output at Pin 2 Having Some glitches

    I am testing LTC2644CMS-L12#PBF assembled in Standalone PCB for Evalution.I am feeding PWM Signal to Pin No.9 With Duty Cycle from 0% to 75% and fixed Frequency of 5.79 KHz.
    Here I measured voltages at every pin of LTC2644 for reference
    Pin No.1 = 5V
    Pin…
