REF
Voltage Reference Input. Reference voltage for analog-to-digital conversion. Apply a reference
voltage between 1V and V
DD
. Bypass REF to GND with a 0.1μF capacitor.
Positive Supply Voltage, +2.375V to +5.25V. Bypass with a 1μF capacitor. Connect to pin 1.
Pen Interrupt Output. Open anode output. 10k
to 100k
pullup resistor required to V
DD
.
Serial Data Output. Data changes state on the falling edge of DCLK. High impedance when
CS
is
HIGH.

BUSY
Busy Output. BUSY pulses high for one clock period before the MSB decision. High impedance when
CS
is HIGH.
14
DIN
Serial Data Input. Data clocked in on the rising edge of DCLK.
15
CS
Active-Low Chip Select. Data is only clocked into DIN when
CS
is low. When
CS
is high, DOUT and
BUSY are high impedance.
16
DCLK
Serial Clock Input. Clocks data in and out of the serial interface and sets the conversion speed (duty
cycle must be 40% to 60%).
