ADS901
DESCRIPTION
The ADS901 is a high-speed pipelined analog-to-
digital converter that operates from a +3V power
supply. This complete converter includes a wide band-
width track/hold and a 10-bit quantizer. The full scale
input range is set by external references.
The ADS901 employs digital error correction tech-
niques to provide excellent differential linearity for
demanding imaging applications. Its low distortion
and high SNR give the extra margin needed for
telecommunications, video and test instrumentation
applications. The ADS901 is available in a 28-lead
SSOP package.

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
specifications.
