REF
Voltage Reference Output/Input. Reference voltage for analog-to-digital conversion. In internal
reference mode, the reference buffer provides a 2.50V nominal output. In external reference mode,
apply a reference voltage between 1V and VDD. Bypass REF to GND with a 0.1F capacitor.
10
VDD
Positive Supply Voltage, +2.375V (2.70V) to +5.25V. External (internal) reference. Bypass with a 1F
capacitor. Connect to pin 1.
11
PENIRQ
Pen Interrupt Output. Open anode output. 10k
Ω to 100kΩ pullup resistor required to VDD.
12
DOUT
Serial Data Output. Data changes state on the falling edge of DCLK. High impedance when CS is
HIGH.
13
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%).
