RDC_SENSE

Reference Buffer Sense Feedback. Connect to RDC

plane.

27, 33, 40, 48,

RDC

Reference Buffer Decoupling. Connect all RDC outputs

together. Bypass to AGND with at least an 80µF total

capacitance. See the Layout, Grounding, and Bypassing

section.

CH0

Channel 0 Analog Input

CH1

Channel 1 Analog Input

CH2

Channel 2 Analog Input

CH3

Channel 3 Analog Input

CH7

Channel 7 Analog Input

Active-Low Write Input. Drive WR low to write to the

ADC. Configuration registers are loaded on the rising

edge of WR.

Active-Low Chip-Select Input. Drive CS low when

reading from or writing to the ADC.

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.
