+VCC
Power Supply Input. The +VCC range for the AD7873 is from 2.2 V to 5.25 V. Both +VCC pins should be
connected directly together.

GND
Analog Ground. Ground reference point for all circuitry on the AD7873. All analog input signals
and any external reference signals should be referred to this GND voltage.

VBAT
Battery Monitor Input. ADC Input Channel 4.

AUX
Auxiliary Input. ADC Input Channel 5.

VREF
Reference Output for the AD7873. Alternatively, an external reference can be applied to this input.
The voltage range for the external reference is 1.0 V to +VCC. For specified performance, it is 2.5 V on
the AD7873. The internal 2.5 V reference is available on this pin for use external to the device. The
reference output must be buffered before it is applied elsewhere in a system. A 0.1 µF capacitor is
recommended between this pin and GND to reduce system noise effects.

PENIRQ
Pen Interrupt. CMOS logic open-drain output (requires 10 kΩ to 100 kΩ pull-up resistor externally).
5
12
DOUT
Data Out. Logic output. The conversion result from the AD7873 is provided on this output as a
serial data stream. The bits are clocked out on the falling edge of the DCLK input. This output is
high impedance when CS is high.
6
13
BUSY
BUSY Output. Logic output. This output is high impedance when CS is high.
7
14
DIN
Data In. Logic Input. Data to be written to the AD7873 control register is provided on this input and
is clocked into the register on the rising edge of DCLK (see the Control Register section).
8
15
CS
Chip Select Input. Active low logic input. This input provides the dual function of initiating
conversions on the AD7873 and enabling the serial input/output register.
9
16
DCLK
External Clock Input. Logic input. DCLK provides the serial clock for accessing data from the part.
This clock input is also used as the clock source for the AD7873 conversion process.
N/A1
EPAD
Exposed Pad. The exposed pad is not connected internally. For increased reliability of the solder
joints and maximum thermal capability, it is recommended that the pad be soldered to the ground
plane.

NOTES
1. THE EXPOSED PAD IS NOT CONNECTED INTERNALLY.
FOR INCREASED RELIABILITY OF THE SOLDER JOINTS
AND MAXIMUM THERMAL CAPABILITY, IT IS
RECOMMENDED THAT THE PAD BE SOLDERED
