NAME
FUNCTION
VNEG
-2.5V Charge-Pump Voltage-Output. Connect a 0.1μF capacitor to GND.
2
32
REF-
Negative Reference Voltage Input. For internal reference operation, connect REF- to
GND. For external reference operation, bypass REF- to GND with a 0.1μF capacitor and
set V
REF-
from -2.2V to +2.2V, provided V
REF+
> V
REF-
.
3
1
REF+
Positive Reference Voltage Input. For internal reference operation, connect a 4.7μF
capacitor from REF+ to GND. For external reference operation, bypass REF+ to GND
with a 0.1μF capacitor and set V
REF+
from -2.2V to +2.2V, provided V
REF+
> V
REF-
.
4
2
AIN+
Positive Analog Input. Positive side of fully differential analog input. Bypass AIN+ to GND
with a 0.1μF or greater capacitor.
5
3
AIN-
Negative Analog Input. Negative side of fully differential analog input. Bypass AIN- to
GND with a 0.1μF or greater capacitor.
6
4
I
SET
Segment Current Controller. Connect to ground through a resistor to set the segment
current. See Table 6 for segment current selection.

5
GND
Ground
8
—
V
DD
Analog and Digital Circuit Supply Voltage. Connect V
DD
to a +2.7V to +5.25V power
supply. Bypass V
DD
to GND with a 0.1μF and a 4.7μF capacitor.
9
8
CLK
External Clock Input. When the EXTCLK register bit is set to one, CLK is the master clock
input (frequency = 4.9152MHz) for the modulator and the filter. When the EXTCLK
register bit is reset to zero, the internal clock is used. Connect CLK to GND or DV
DD
(MAX1499) or V
DD
(MAX1497) when the internal oscillator is used.
10
9
EOC
Active-Low End-of-Conversion Logic Output. A logic low at EOC indicates that a new
ADC result is available in the ADC result register.
11
10
CS
Active-Low Chip Select Input. Forcing
CS
low activates the serial interface.
12
11
DIN
Serial Data Input. Data present at DIN is shifted into the internal registers in response to
a rising edge at SCLK when
CS
is low.
13
12
SCLK
Serial Clock Input. Apply an external clock to SCLK to facilitate communication through
the serial bus. SCLK may idle high or low.
14
13
DOUT
Serial Data Output. DOUT presets serial data in response to register queries. Data shifts
out on the falling edge of SCLK. DOUT goes high impedance when
CS
is high.
