dsADC_CONGIG Description
NC_MCLKO_MCLKI_MDAC
VIN_MDAT
ANALOG integrated internal ADC mode, MCLK not connected (NC)
VIN (analog)
VIN_MDAT is analog input VIN
MCLKO external dsModulator (e.g. MCLK output
AD7403) with MCLK input
MDAT input
MDAT input
driven by MCLKO
MCLKI external dsModulator (e.g. MCLK input
AD7400) with MCLK output
that drives MCLKI
MDAC external dsModulator (e.g. MDAC output (= MCLK out) MDAT input for CMP
LM339, LM319) realized by
external comparator CMP with
two R and one C
