PENIRQ
Power Supply, 2.7V to 5V.
X+ Position Input. ADC input Channel 1.
Y+ Position Input. ADC input Channel 2.
X– Position Input.
Y– Position Input.
Ground
Auxiliary Input 1. ADC input Channel 3.
Auxiliary Input 2. ADC input Channel 4.
Voltage Reference Input
Power Supply, 2.7V to 5V.
Pen Interrupt. Open anode output (requires 10k
to 100k
pull-up resistor externally).
Serial Data Output. Data is shifted on the falling
edge of DCLK. This output is high impedance
when CS is HIGH.
Busy Output. This output is high impedance when
CS is HIGH.
Serial Data Input. If CS is LOW, data is latched on
rising edge of DCLK.
Chip Select Input. Controls conversion timing and
enables the serial input/output register.
External Clock Input. This clock runs the SAR con-
version process and synchronizes serial data I/O.

NOTE: (1) Stresses above those listed under “Absolute Maximum Ratings”
may cause permanent damage to the device. Exposure to absolute maximum
conditions for extended periods may affect device reliability.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published specifi-
cations.

NOTES: (1) For detailed drawing and dimension table, please see end of data sheet, or Appendix C of Burr-Brown IC Data Book. (2) Models with a slash (/) are
available only in Tape and Reel in the quantities indicated (e.g., /2K5 indicates 2500 devices per reel). Ordering 2500 pieces of “ADS7843E/2K5” will get a single
2500-piece Tape and Reel. For detailed Tape and Reel mechanical information, refer to Appendix B of Burr-Brown IC Data Book.
