Three-State Digital I/O Line (D0)
INT goes low when the conversion is complete and output data is ready.
Active-Low Read Select. If CS is low, a falling edge on RD enables the read
operation on the data bus.
Active-Low Write Select. When CS is low in the internal acquisition mode, a rising
edge on WR latches in configuration data and starts an acquisition plus a conver-
sion cycle. When CS is low in external acquisition mode, the first rising edge on WR
ends acquisition and starts a conversion.
Clock Input. In external clock mode, drive CLK with a TTL/CMOS-compatible clock.
In internal clock mode, connect this pin to either VDD or GND.

Analog and Digital Ground
Bandgap Reference Output/Bandgap Reference Buffer Input. Bypass to GND with
a 0.01F capacitor. When using an external reference, connect REFADJ to VDD to
disable the internal bandgap reference.
Analog Input Channel 2
Analog Input Channel 1
Analog Input Channel 0
Ground Reference for Analog Inputs. Sets zero-code voltage in single-ended mode
and must be stable to ±0.5 LSB during conversion.
Analog Input Channel 3
Analog Input Channel 4
Analog Input Channel 5
Active-Low Chip Select. When CS is high, digital outputs (INT, D11–D0) are high
impedance.
