FUNCTION
Analog Supply Input. Bypass AVDD to AGND with a
0.1µF capacitor at each AVDD input.
Analog Ground. Connect all AGND inputs together.
Channel 0 Analog Input
Channel 1 Analog Input
Channel 2 Analog Input
Channel 3 Analog Input
External Reference Input/Internal Reference Output.
Place a 0.1µF capacitor from REFIO to AGND.
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 15
16-Bit Parallel Data Bus Digital Output Bit 14
Internally Connected. Connect to AGND.
Exposed Pad. Internally connected to AGND. Connect to
a large ground plane to maximize thermal performance.
Not intended as an electrical connection point.
