NAME
FUNCTION
1
31
VNEG
-2.5V Charge-Pump Voltage Output. Connect a 0.1F capacitor to GND.
232
REF-
Negative Reference Voltage Input. For internal-reference operation, connect REF- to GND.
For external-reference operation, bypass REF- to GND with a 0.1F capacitor and set VREF-
from -2.2V to +2.2V, provided VREF+ > VREF-.
31
REF+
Positive Reference Voltage Input. For internal-reference operation, connect a 4.7F
capacitor from REF+ to GND. For external-reference operation, bypass REF+ to GND with a
0.1F capacitor and set VREF+ from -2.2V to +2.2V, provided VREF+ > VREF-.
42
AIN+
Positive Analog Input. Positive side of fully differential analog input. Bypass AIN+ to GND
with a 0.1F or greater capacitor.
53
AIN-
Negative Analog Input. Negative side of fully differential analog input. Bypass AIN- to GND
with a 0.1F or greater capacitor.
64
ISET
Segment Current Controller. Connect to ground through a resistor to set the segment
current. See Table 5 for current selection.
75
GND
Ground
8—
VDD
Analog and Digital Circuit Supply Voltage. Connect VDD to a +2.7V to +5.25V power supply.
Bypass VDD to GND with a 0.1F capacitor and a 4.7F capacitor.
98
INTREF
Internal-Reference Logic Input. Connect to GND to select external-reference mode. Connect
to DVDD for the MAX1447/MAX1498 and VDD for the MAX1496 to select the internal-
reference mode.
10
9
RANGE
Range Logic Input. RANGE controls the fully differential analog input range. Connect to
GND for the ±2V input range. Connect to DVDD (MAX1447/MAX1498) or VDD (MAX1496) for
the ±200mV input range.
11
10
DPSET1
Decimal-Point Logic-Input 1. Controls the decimal point of the LED. See the Decimal-Point
Control section.
12
11
DPSET2
Decimal-Point Logic-Input 2. Controls the decimal point of the LED. See the Decimal-Point
Control section.
13
12
PEAK
Peak Logic Input. Connect to DVDD (MAX1447/MAX1498) or VDD (MAX1496) to display the
highest ADC value on the LED. Connect to GND to disable the peak function.
14
13
HOLD
Hold Logic Input. Connect to DVDD (MAX1447/MAX1498) or VDD (MAX1496) to hold the
current ADC value on the LED. Connect to GND to update the LED at a rate of 2.5Hz and
disable the hold function. For the MAX1447, only placing the device into hold mode initiates
an offset mismatch calibration. Assert HOLD high for a minimum of 2s to ensure the
completion of offset mismatch calibration.
