V
CC
(Pin 1):
Positive Supply Voltage. Bypass to GND
(Pin1) with a 10
μ
F tantalum capacitor in parallel with
0.1
μ
F ceramic capacitor as close to the part as possible.
REF
+
(Pin 2), REF
–
(Pin 3):
Differential Reference Input.
The voltage on these pins can have any value between GND
and V
CC
as long as the reference positive input, REF
+
, is
maintained more positive than the reference negative
input, REF
–
, by at least 0.1V.
IN
+
(Pin 4), IN
–
(Pin 5):
Differential Analog Input. The
voltage on these pins can have any value between
GND – 0.3V and V
CC
+ 0.3V. Within these limits the
converter bipolar input range (V
IN
= IN
+
– IN
–
) extends
from –0.5 (V
REF
) to 0.5 (V
REF
). Outside this input range
the converter produces unique overrange and underrange
output codes.
GND (Pin 6):
Ground. Connect this pin to a ground plane
through a low impedance connection.
CS (Pin 7):
Active LOW Digital Input. A LOW on this pin
enables the SDO digital output and wakes up the ADC.
Following each conversion the ADC automatically enters
the Sleep mode and remains in this low power state as
long as CS is HIGH. A LOW-to-HIGH transition on CS
during the Data Output transfer aborts the data transfer
and starts a new conversion.
SDO (Pin 8):
Three-State Digital Output. During the Data
Output period this pin is used as the serial data output.
When the chip select CS is HIGH (CS = V
CC
) the SDO pin
is in a high impedance state. During the Conversion and
Sleep periods this pin is used as the conversion status
output. The conversion status can be observed by pulling
CS LOW.
SCK (Pin 9):
Bidirectional Digital Clock Pin. In Internal
Serial Clock Operation mode, SCK is used as the digital
output for the internal serial interface clock during the Data
Output period. In External Serial Clock Operation mode,
SCK is used as the digital input for the external serial
interface clock during the Data Output period. A weak
internal pull-up is automatically activated in Internal Serial
Clock Operation mode. The Serial Clock Operation mode is
determined by the logic level applied to the SCK pin at
power up or during the most recent falling edge of CS.
F
O
(Pin 10):
Frequency Control Pin. Digital input that
controls the ADC’s notch frequencies and conversion
time. When the F
O
pin is connected to V
CC
(F
O
= V
CC
), the
converter uses its internal oscillator and the digital filter
first null is located at 50Hz. When the F
O
pin is connected
to GND (F
O
= OV), the converter uses its internal oscillator
and the digital filter first null is located at 60Hz. When F
O
is driven by an external clock signal with a frequency f
EOSC
,
the converter uses this signal as its system clock and the
digital filter first null is located at a frequency f
EOSC
/2560.
