High Byte Enable. Used to multiplex the 10-bit conversion result.
1: 2 MSBs are multiplexed on the data bus.
0: 8 LSBs are available on the data bus.

INT goes low when the conversion is complete and the 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 internal acquisition mode, a rising edge on WR
latches in configuration data and starts an acquisition plus a conversion 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 inter-
nal clock mode, connect this pin to either V

Ground Reference for Analog Inputs. Sets zero-code voltage in single-ended mode and
must be stable to ±0.5 LSB during conversion.
Analog and Digital Ground
Bandgap Reference Output/Bandgap Reference Buffer Input. Bypass to GND with a 0.01µF
capacitor. When using an external reference, connect REFADJ to V
bandgap reference.
Bandgap Reference Buffer Output/External Reference Input. Add a 4.7µF capacitor to GND
when using the internal reference.
Analog +5V Power Supply. Bypass with a 0.1µF capacitor to GND.
Digital Power Supply. V
