  • RE: REF6041: About the output impedance

    Hello, REF6x would be able to work with ADS8881 to preserve the performance of the ADC as specified in the datasheet, and it is used on ADS8881EVM2-PDK. We have more precise and accurate voltage references such as REF54 and REF70, but those would require…

  • RE: REF102: REF102BU

    Hi Ajeet, If you are looking for a noise requirement of <4µVpp and a temperature coefficient of less than 5ppm/°C, I would suggest the REF70 instead of the REF102. According to the REF70 datasheet, it will stay below 4µVpp noise, and…

  • RE: OPA182: Need some help with an OP AMP in my circuit!

    Hi Eric, We have some great selection of voltage references in the link below. For instance, REF35 , REF50xx , REF60xx , REF70 and many other low cost, low noise, very low drift precision voltage reference for the ADC application. https://www.ti.com/power-management…
