Pin Description
NAME
FUNCTION
1
HBEN
High Byte Enable. Used to multiplex the 12-bit conversion result.
1: Four MSBs are multiplexed on the data bus.
0: Eight LSBs are available on the data bus.
PIN
2
D7
Tri-State Digital I/O Line (D7)
3
D6
Tri-State Digital I/O Line (D6)
4
D5
Tri-State Digital I/O Line (D5)
5
D4
Tri-State Digital I/O Line (D4)
6
D3/D11
Tri-State Digital I/O Line (D3, HBEN = 0; D11, HBEN = 1)
7
D2/D10
Tri-State Digital I/O Line (D2, HBEN = 0; D10, HBEN = 1)
8
D1/D9
Tri-State Digital I/O Line (D1, HBEN = 0; D9, HBEN = 1)
9
D0/D8
Tri-State Digital I/O Line (D0, HBEN = 0; D8, HBEN = 1)
10
INT
INT goes low when the conversion is complete and the output data is ready.
11
RD
Active-Low Read Select. If CS is low, a falling edge on RD enables 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 VDD or GND.
14
CS
Active-Low Chip Select. When CS is high, digital outputs (D7–D0) are high impedance.

23
COM
Ground Reference for Analog Inputs. Sets zero-code voltage in single-ended mode and
must be stable to ±0.5 LSB during conversion.
24
GND
Analog and Digital Ground
25
REFADJ
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.
26
REF
Bandgap Reference Buffer Output/External Reference Input. Add a 4.7F capacitor to GND
when using the internal reference.
27
VDD
Analog +5V Power Supply. Bypass with a 0.1F capacitor to GND.
28
VLOGIC
Digital Power Supply. VLOGIC powers the digital outputs of the data converter and can range
from +2.7V to (VDD + 300mV).
