Pin Description
NAME
1
HBEN
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.

Three-State Digital I/O Line (D2)
Three-State Digital I/O Line (D1, HBEN = 0; D9, HBEN = 1)
Three-State Digital I/O Line (D0, HBEN = 0; D8, HBEN = 1)
INT
goes low when the conversion is complete and the output data is ready.
D1/D9
D0/D8
INT
11
RD
Active-Low Read Select. If
CS
is low, a falling edge on
RD
will enable the read operation
on the data bus.
12
WR
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.
13
CLK
Clock Input. In external clock mode, drive CLK with a TTL/CMOS-compatible clock. In
internal clock mode, connect this pin to either V
DD
or GND.
14
CS
Active-Low Chip Select. When
CS
is high, digital outputs (
INT
, D7–D0) are high imped-
ance.

23
COM
Ground Reference for Analog Inputs. Sets zero-code voltage in single-ended mode and
must be stable to ±0.5LSB during conversion.
24
GND
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
DD
to disable
the internal bandgap reference.
25
REFADJ
26
REF
Bandgap Reference Buffer Output/External Reference Input. Add a 4.7μF capacitor to
GND when using the internal reference.
27
V
DD
Analog +5V Power Supply. Bypass with a 0.1μF capacitor to GND.
28
V
LOGIC
Digital Power Supply. V
LOGIC
powers the digital outputs of the data converter and can
range from +1.8V to V
DD
+ 300mV.
