—
IN4
Analog Input. Analog input to the positive mux only.
5
3
IN0
Analog Input. Analog input to both the positive and negative mux.
6
4
REF
1.25V Reference Buffer Output/External Reference Input. Reference voltage
for the ADC and the DAC. Connect a 4.7F capacitor to REF between REF
and AGND.
7
5
AGND
Analog Ground. Reference point for the analog circuitry. AGND connects to
the IC substrate.
88
6
AVDD
Analog Supply Voltage
9
7
CPLL
PLL Capacitor Connection Pin. Connect an 18nF ceramic capacitor between
CPLL and AVDD.
10
8
WU1
Active-Low Wake-Up Input. Internally pulled up. The device will wake-up from
Sleep mode to Standby mode when WU1 is asserted.
11
9
WU2
Active-Low Wake-Up Input. Internally pulled up. The device will wake-up from
Sleep mode to Standby mode when WU2 is asserted.
12
10
RESET
Active-Low RESET Output. It remains low while AVDD is below the threshold
and stays low for a timeout period after AVDD rises above the threshold.
RESET is an open-drain output.
13
—
IN1
Analog Input. Analog input to both the positive and negative mux.
14
—
IN2
Analog Input. Analog input to both the positive and negative mux.
15
—
SHDN
Programmable Shutdown Output. Goes low in Sleep mode.
16
—
DRDY
Active-Low Data Ready Output. A logic low indicates that a new conversion
result is available in the Data register. DRDY returns high upon completion of
a full output word read operation. DRDY also signals the end of an ADC
offset-calibration.
17
11
FOUT
2.4576MHz Clock Output. FOUT can be used to drive the input clock of a P.
18
12
CLKOUT
32kHz Crystal Output. Connect a 32kHz crystal between CLKIN and
CLKOUT.
19
13
CLKIN
32kHz Crystal Input. Connect a 32kHz crystal between CLKIN and CLKOUT.
