  • ADC14155QML-SP: Analog Rail lost power

    Resolved
    Part Number: ADC14155QML-SP Tool/software: Hi, If the VA and VD (3.3V) suddenly lost power (0V) while VDR (1.8V) is still on, would this cause any stress to this ADC or latency failure? We are currently using this part for an IRAD, so I would like to…

  • ADC14155QML-SP: IBIS model for digital interface

    TI Thinks Resolved
    Part Number: ADC14155QML-SP Is there an ibis model available for simulating the digital interface?

  • ADC14155QML-SP: power sequencing

    TI Thinks Resolved
    Part Number: ADC14155QML-SP The part requires three voltages: Va (3.3 V), Vd (3.3 V), and Vdr (1.8 V). The datasheet indicates that Va and Vd shouldn’t be greater than 100 mV apart, so that implies they should be supplied by the same voltage regulator…
