DESCRIPTION
The ADS931 is a high speed pipelined analog-to-
digital converter that is specified to operate from
standard +5V or +3V power supplies. This converter
includes a high bandwidth track/hold and an 8-bit
quantizer. The performance is specified with a single-
ended input range of 1V to 2V when operating off of
a +3V supply. This device also allows for standard
input ranges such as 2V to 4V or 2V to 3V, when
operating on +5V supplies. The full scale input range
is set by an external reference.
The ADS931 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 telecom-
munications, video and test instrumentation applica-
tions. This high performance A/D converter is speci-
fied for performance at a 30MHz sampling rate. The
ADS931 is available in a 28-Lead SSOP package.
