GND (Pins 1, 7, 8, 9, 10, 15, 16): Ground. Multiple ground
pins internally connected for optimum ground current flow
and V
ground plane through a low impedance connection. All seven
pins must be connected to ground for proper operation.

0.1 F ceramic capacitor as close to the part as possible.

bipolar input range (V
(V
produces unique overrange and underrange output codes.
CS (Pin 11): 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 12): Three-State Digital Output. During the Data
Output period, this pin is used as serial data output. When

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 13): Bidirectional Digital Clock Pin. In Internal
Serial Clock Operation mode, SCK is used as digital output
for the internal serial interface clock during the Data
Output period. In External Serial Clock Operation mode,
SCK is used as 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 Op-
eration mode. The Serial Clock Operation mode is deter-
mined by the logic level applied to the SCK pin at power up
or during the most recent falling edge of CS.
F
controls the ADC’s notch frequencies and conversion
time. When the F
converter uses its internal oscillator and the digital filter
rejects 50Hz and 60Hz simultaneously. When the F
driven by an external clock signal with a frequency f
the converter uses this signal as its system clock and the
digital filter has 87dB minimum rejection in the range
