Figure 17: Delta Sigma ADC Configurations dsADC_CONFIG (internal: ANALOG vs. external: MCLKO, MCLKI, MDAC)
dsADC_CONGIG Description NC_MCLKO_MCLKI_MDAC VIN_MDAT
ANALOG integrated internal ADC mode,
VIN_MDAT is analog input VIN
MCLK not connected (NC) VIN (analog)
MCLKO external dsModulator (e.g.
AD7403) with MCLK input
driven by MCLKO
MCLK output MDAT input
MCLKI external dsModulator (e.g.
AD7400) with MCLK output
that drives MCLKI
MCLK input MDAT input
MDAC external dsModulator (e.g.
LM339) realized by external
comparator CMP with two R
and one C
MDAC output (= MCLK out) MDAT input for CMP
