DESCRIPTION

The ADS830 is a pipeline, CMOS Analog-to-Digital (A/D)

converter 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 SSOP-20 package

and is pin-for-pin compatible with the 8-bit, 80MHz ADS831.
