ADS5263: 16 bits mode

Gauthier Auvray
Prodigy 110 points

Part Number: ADS5263

Hi,

We intend to use ads5263 quad ADC in 16 bits mode only.

We don't plan to use 14bits mode. The designer has shorted 14 bits inputs (INxB) to ground.

Is it correct?

Best regards,

Gauthier Auvray

    Hi Gauthier,
    How are you?
    Thanks for using ADS5263 device.
    For this question, first, please look at the ADS5263
    schematics from the User's Guide on the TI website.
    When you don't plan to use 14bit mode (such as INxB_P and INxB_M input pins)
    and want to short these input pins to ground.
    Then, we suggest please connect these INxB_P and INxB_M pins with
    each pin connected to a 0.1uF cap in series to Ground Plane.

    Thanks and best regards,
    Chen
