ADS7826: VREF(Max) at Vcc = 3.3V

Part Number: ADS7826

Hello,

My customer has a question about ADS7826.

[Q]

In the data sheet of the ADS7826, it is stated that VREF(Max) = Vcc - 0.2 V at  Vcc = 2.7 to 3.6 V.
My customers want to use Vcc 3.3V.
Is it possible to use the circuit of Figure 40 in the data sheet at this time?


Best Regards,

Kaede Kudo


  • Hi Kaede Kudo

    For your use case of VCC = 3.3V, you can not tie VREF and VCC pin together as shown in figure 40 of datasheet. VREF = VCC is true for VCC =5V.

    We need to get figure 40 corrected as per that. Thanks for pointing this out

    Thanks & Regards

    Abhijeet
