    Hi Matej,

    Figure 2 in the ADS2152 datasheet shows an example REF3140 and OPA350 reference circuit. However, I would actually recommend using a REF5040 or REF6x40. These references were released after the ADS1252 and are well-suited for high-resolution ADCs. They also have buffered outputs, so you wouldn't need the OPA350 that is shown in figure 2.

    Best regards,
    Chris
