DESCRIPTION
The ADS830 is a pipeline, CMOS analog-to-digital con-
verter that operates from a single +5V power supply. This
converter provides excellent performance with a single-
ended input and can be operated with a differential input
for added spurious performance. This high performance
converter includes an 8-bit quantizer, high bandwidth
track/hold, and a high accuracy internal reference. It also
allows for the user to disable the internal reference and
utilize external references. This external reference option
provides excellent gain and offset matching when used in
multi-channel applications or in applications where DC full
scale range adjustment is required.
The ADS830 employs digital error correction techniques to
provide excellent differential linearity for demanding im-
aging applications. Its low distortion and high SNR give
the extra margin needed for medical imaging, communica-
tions, video, and test instrumentation.
The ADS830 is specified at a maximum sampling fre-
quency of 60MHz and a single-ended input range of 1.5V
to 3.5V. The ADS830 is available in a 20-lead SSOP
package and is pin-for-pin compatible with the 8-bit, 80MHz
ADS831.
