ADS8322YB Burr-Brown Corporation, ADS8322YB Datasheet - Page 2

• Manufacturer Part Number: ADS8322YB
• Description: 16-Bit/ 500kHz/ MicroPower Sampling ANALOG-TO-DIGITAL CONVERTER
• Manufacturer: Burr-Brown Corporation

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.
PACKAGE/ORDERING INFORMATION
2
This integrated circuit can be damaged by ESD. Texas Instru-
ments 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 specifications.
PIN ASSIGNMENTS
NOTE: (1) Models with a slash (/) are available only in Tape and Reel in the quantities indicated (e.g., /2K indicates 2000 devices per reel). Ordering 2000 pieces
of “ADS8322Y/2K” will get a single 2000-piece Tape and Reel.

DESCRIPTION
An external CMOS compatible clock can be applied
to the CLOCK input to synchronize the conversion
process to an external source.
Convert Start
Synchronization pulse for the parallel output.
Selects 8 most significant bits (LOW) or 8 least
significant bits (HIGH). Data valid on pins 9-16.

Reference Output. A 0.1 F capacitor should be con-
nected to this pin when the internal reference is
used.
