NAME FUNCTION
37 34 32 CH2 Channel 2 Analog Input
39 37 34 CH3 Channel 3 Analog Input
— 39 37 CH4 Channel 4 Analog Input
— 42 39 CH5 Channel 5 Analog Input
— — 42 CH6 Channel 6 Analog Input
— — 45 CH7 Channel 7 Analog Input
52 52 52 WR
Active-Low Write Input. Drive WR low to write to the ADC. Configuration
registers are loaded on the rising edge of WR.
53 53 53 CS
Active Low-Chip Select Input. Drive CS low when reading from or writing to
the ADC.
54 54 54 RD
Active-Low Read Input. Drive RD low to read from the ADC. Each rising edge
of RD advances the channel output on the data bus.
