CH0 to CH15 (Pin 21 to Pin 28 and Pin 1 to Pin 8):
Analog
Inputs. May be programmed for single-ended or differen-
tial mode. CH8 to CH15 (Pin 1 to Pin 8) not connected on
the LTC2414.
V
CC
(Pin 9):
Positive Supply Voltage. Bypass to GND
(Pin 15) with a 10
μ
F tantalum capacitor in parallel with
0.1
μ
F ceramic capacitor as close to the part as possible.
COM (Pin 10):
The common negative input (IN
–
) for all
single-ended multiplexer configurations. The voltage on
Channel 0 to 15 and COM input pins can have any value
between GND – 0.3V and V
CC
+ 0.3V. Within these limits,
the two selected inputs (IN
+
and IN
–
) provide a bipolar
input range (V
IN
= IN
+
– IN
–
) from –0.5 V
REF
to 0.5 V
REF
.
Outside this input range, the converter produces unique
overrange and underrange output codes.
REF
+
(Pin 11), REF
–
(Pin 12):
Differential Reference
Input. The voltage on these pins can have any value
between GND and V
CC
as long as the positive reference
input, REF
+
, is maintained more positive than the negative
reference input, REF
–
, by at least 0.1V.
GND (Pin 15):
Ground. Connect this pin to a ground plane
through a low impedance connection.
CS (Pin 16):
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 17):
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 18):
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 19):
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
= 0V), 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 converters use this signal as their system clock and the
digital filter first null is located at a frequency f
EOSC
/2560.
SDI (Pin 20):
Serial Digital Data Input. During the Data
Output period, this pin is used to shift in the multiplexer
address started from the first rising SCK edge. During the
Conversion and Sleep periods, this pin is in the DON’T
CARE state. However, a HIGH or LOW logic level should be
maintained on SDI in the DON’T CARE mode to avoid an
excessive current in the SDI input buffers.
NC Pins:
Do Not Connect.
