DAC7631: Ripple

Ray Vincent Aranzaso

Part Number: DAC7631


Hi,

Good Day.

Can you provide the tolerances of voltages of VREFH and VREFL for the DAC7631E? As far as we understand it could range between -2.5 V and +2.5 V. What is the allowed ripple on that voltage?

Please advise. Thank you very much.

Best Regards,

Ray Vincent

    Hello Ray, 

    Please refer to the absolute maximum rating table on page 4 of the data sheet. The device can operate beyond the conditions you have specified as is shown on the maximum rating table. 

    The reference input is not filtered by the device, so the output ripple would be similar to the noise from the power supply. Use a bypass capacitor to reduce noise. 

    Thank you,
