Circuit providing a plurality of AD sampling references

The utility model discloses a circuit providing a plurality of AD sampling references. The circuit comprises a reference power input terminal and a ground terminal. Between the reference power input terminal and the ground terminal, one or more high-precision resistance bleeder circuits are connected in parallel. The high-precision resistance bleeder circuits are formed by two high-precision resistors connected in series. AD sampling reference output ends extend out from midpoints of the two connected high-precision resistors. The circuit providing the plurality of AD sampling references provides a plurality of different AD sampling references. In a sampling process, through selecting different references, precision of AD sampling values is improved, and error of the AD sampling values is reduced.
