DESCRIPTION
The ADS902 is a high speed pipelined analog-to-
digital converter that is specified to operate from a
single +5V supply. This converter includes a wide
bandwidth track/hold and a 10-bit quantizer. The per-
formance is specified with a single-ended input range
of 2.25V to 3.25V, or 2V to 4V. The input range is set
by the external reference values.
The ADS902 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 tele-
communications, video and test instrumentation appli-
cations. This high performance A/D converter is speci-
fied to operate at a 30MHz sampling rate. The ADS902
is available in a 28-pin SSOP package.
