Mode Selection Input. Internally pulled low with a 50µA current source. MODE = 0 acti-
vates read mode; MODE = 1 activates write-read mode (see Digital Interface Section).
Three-State Data Output (LSB)
Three-State Data Outputs
Read Input. RD must be low to access data (see Digital Interface section).
Interrupt Output. INT goes low to indicate end of conversion (see Digital Interface
section).
Ground
Lower Limit of Reference Span. REF- sets the zero-code voltage. Range is GND ≤
V
Upper Limit of Reference Span. REF+ sets the full-scale input voltage. Range is V
< V
Write-Control Input/Ready-Status Output (see Digital Interface section)
Chip-Select Input. CS must be low for the device to recognize WR or RD inputs.
