Channel 3 Analog Input
Channel 4 Analog Input
Channel 5 Analog Input
Channel 6 Analog Input
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.

16-Bit Parallel Data Bus Digital Output Bit 14
Exposed Pad. Internally connected to AGND. Connect to a large ground
plane to maximize thermal performance. Not intended as an electrical
connection point.
