ADS1261: Internal Reference vs RefOut

Part Number: ADS1261

Are the internal references and the REFOUT pin coming from the same buffered regulator?

    Hi Paul Carney,

    See below for the ADS1261 VREF block diagram. The internal VREF is buffered before it reaches the ADC and before the REFOUT pin (this is not shown in the block diagram). This is why the REFOUT pin can drive +/-10mA.
