ADS930
DESCRIPTION
The ADS930 is a high speed pipelined analog-to-
digital converter specified to operate from nominal
+3V or +5V power supplies with tolerances of up to
10%. This complete converter includes a high band-
width track/hold, a 8-bit quantizer and an internal
reference.
The ADS930 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.
This high performance A/D converter is specified for
performance at a 30MHz sampling rate. The ADS930
is available in a 28-lead SSOP package.
