Digital Ground
DGND
28
+5V Supply. Bypass with 0.1F capacitor to AGND.
VDD
27
INT goes low when conversion is complete and output data is ready.
INT
24
Bandgap Voltage-Reference Output / External Adjust Pin. Bypass with a 0.01F capacitor to AGND.
Connect to VDD when using an external reference at the REF pin.
REFADJ
25
Reference Buffer Output / ADC Reference Input. In internal reference mode, the reference buffer provides a
4.096V nominal output, externally adjustable at REFADJ. In external reference mode, disable the internal
buffer by pulling REFADJ to VDD.
REF
26
Three-State Digital I/O. D2 output (HBEN = low), D10 output (HBEN = high).
D2/D10
12
Three-State Digital I/O. D1 output (HBEN = low), D9 output (HBEN = high).
D1/D9
13
Three-State Digital I/O. D0 output (HBEN = low), D8 output (HBEN = high). D0 = LSB.

Used to multiplex the 12-bit conversion result. When high, the 4 MSBs are multiplexed on the data bus;
when low, the 8 LSBs are available on the bus.
HBEN
5
Shutdown. Puts the device into full power-down (FULLPD) mode when pulled low.
SHDN

Three-State Digital I/O
D7–D4
7–10
Three-State Digital I/O. D3 output (HBEN = low), D11 output (HBEN = high).
D3/D11

When CS is low, a falling edge on RD will enable a read operation on the data bus.
RD
4
When CS is low, in the 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 the external acquisition mode, the first rising edge on
WR starts an acquisition and a second rising edge on WR ends acquisition and starts a conversion cycle.

PIN
Chip Select, active low.
CS
2
Clock Input. In external clock mode, drive CLK with a TTL/CMOS compatible clock. In internal clock mode,
place a capacitor (CCLK) from this pin to ground to set the internal clock frequency; fCLK = 1.56MHz typical
with CCLK = 100pF.
