pin Functions
GND (Pins 1, 3, 4, 5, 6, 31, 32, 33): Ground. Multiple
groundpinsinternallyconnectedforoptimumgroundcur-
rent flow and VCC decoupling. Connect each one of these
pins to a common ground plane through a low impedance
connection. All eight pins must be connected to ground
for proper operation.
NC (Pin 2): No Connection. This pin can be left floating
or tied to GND.
COM (Pin 7): The Common Negative Input (IN–) for All
Single-Ended Multiplexer Configurations. The voltage on
CH0 to CH15 and COM pins can have any value between
GND – 0.3V to VCC + 0.3V. Within these limits, the two
selected inputs (IN+ and IN–) provide a bipolar input range
VIN = (IN+ – IN–) from –0.5 VREF/Gain to 0.5 VREF/Gain.
Outside this input range, the converter produces unique
overrange and underrange output codes.
CH0 to CH15 (Pins 8 to 23): Analog Inputs. May be pro-
grammed for single-ended or differential mode.
MUXOUTP (Pin 24): Positive Multiplexer Output. Used
to drive an external buffer/amplifier or can be shorted
directly to ADCINP.
ADCINP (Pin 25): Positive ADC Input. Tie to the output
of a buffer/amplifier driven by MUXOUTP or tie directly
to MUXOUTP.
ADCINN (Pin 26): Negative ADC Input. Tie to the output
of a buffer/amplifier driven by MUXOUTN or tie directly
to MUXOUTN.
MUXOUTN (Pin 27): Negative Multiplexer Output. Used
to drive an external buffer/amplifier or can be shorted
directly to ADCINN.
VCC(Pin28):PositiveSupplyVoltage.BypasstoGNDwith
a 10F tantalum capacitor in parallel with a 0.1F ceramic
capacitor as close to the part as possible.
REF+(Pin29),REF–(Pin30):DifferentialReferenceInput.
The voltage on these pins can have any value between
GNDandVCCaslongasthereferencepositiveinput,REF+,
remains more positive than the negative reference input,
REF–,byatleast0.1V.ThedifferentialvoltageVREF=(REF+
– REF–) sets the full-scale range (–0.5 VREF/Gain to 0.5
VREF/Gain) for all input channels. When performing an
on-chip temperature measurement, the minimum value
of REF = 2V.
