• AD7928 Track-and-Hold Acquisition Time

    Hi, All!

    The AD7928 ADC input is supplied with a pulsed signal of ~1us duration. The ADC will make a acquisition for 300 ns after falling edge of CS signal and then will do the conversion for several SCLK cycles. The changing the input signal after acquisition…

  • Type of power supply recommended for the AD7928?

    Hello,

    I'm planning to use a Low Dropout regulator LT1129 to supply the power to a AD7928. Since the reference Input voltage to this ADC requires +/-1% for specified performance, I wonder if the use of a switching supply is recommended?.

    How much…

  • LT1129-5 vs ADP7102 for providing power to the AD7928?

    Hello,

    I would like to know if you could provide some facts in terms of specifications for the LT1129-5 and ADP7102 that can help to define which fits better for providing power to the AD7928.

    I wonder if I can use a switching supply along with the LT1129…

  • AD7928 input range and Vdrive

    Hello

    I would like to use AD7927 at VDD=5V, Vdrive=3.3V and input range =0~2*REFin.

    Can I use AD7928 at this condition ?

    The datasheet rev.E P.3 says below about 0~2*REFin  input range.

    "RANGE bit set to 0, AVDD/VDRIVE = 4.75 V to 5.25 V"
