8-Bit, 80MHz Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

● HIGH SNR: 49dB

DESCRIPTION

The ADS831 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.

● INTERNAL/EXTERNAL REFERENCE

OPTION

● SINGLE-ENDED OR

DIFFERENTIAL ANALOG INPUT

● PROGRAMMABLE INPUT RANGE:

1Vp-p /2Vp-p

● LOW POWER: 275mW

● LOW DNL: 0.35LSB

● SINGLE +5V SUPPLY OPERATION

● 20-PIN SSOP PACKAGE

The ADS831 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.

APPLICATIONS

● MEDICAL IMAGING

The ADS831 is specified at a maximum sampling fre-

quency of 80MHz and a single-ended input range of 1.5V

to 3.5V. The ADS831 is available in a 20-lead SSOP

package and is pin-for-pin compatible with the 8-bit, 60MHz

ADS830.
