TERMINAL FUNCTIONS
PIN
I/O
DESCRIPTION
NAME
NO.
AGND
1, 2, 4, 5,
–
Analog ground pins. AGND must be shorted to analog ground plane below the device.
15, 18, 19
BDGND
21
–
Digital ground for all digital inputs and outputs. BDGND must be shorted to the analog ground plane below
the device.
BUSY
22
O
Status output. This pin is high when conversion is in progress.
CONVST
25
I
Convert start. This signal is qualified with CS internally.
CS
26
I
Chip select
FS
27
I
Frame sync. This signal is qualified with CS internally.
+IN
11
I
Noninverting analog input channel
–IN
12
I
Inverting analog input channel
NC
10, 13
–
No connection
PD
28
I
Power down. Device resets and powers down when this signal is high.
REFIN
8
I
Reference (positive) input. REFIN must be decoupled with REFM pin using 0.1-
F bypass capacitor and
1-
F storage capacitor.
REFM
7
I
Reference ground. To be connected to analog ground plane.
REFOUT
9
O
Internal reference output. Shorted to REFIN pin only when internal reference is used.
SCLK
24
I
Serial clock. Data is shifted onto SDO with the rising edge of this clock. This signal is qualified with CS
internally.
SDO
23
O
Serial data out. All bits except MSB are shifted out at the rising edge of SCLK.
