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 “ADS7841/2K5” 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.

Power Supply, 2.7V to 5V.
Analog Input Channel 0.
Analog Input Channel 1.
Analog Input Channel 2.
Analog Input Channel 3.
Ground Reference for Analog Inputs. Sets zero code voltage in single-ended mode. Connect this pin to ground or ground reference
point.
Shutdown. When LOW, the device enters a very low power shutdown mode.
Voltage Reference Input
Power Supply, 2.7V to 5V.
Ground
Conversion Mode. When LOW, the device always performs a 12-bit conversion. When HIGH, the resolution is set by the MODE bit in
the CONTROL byte.
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 conversion 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.
