ADS831

SBAS087A – MAY 2001

8-Bit, 80MHz Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

● HIGH SNR: 49dB

DESCRIPTION

The ADS831 is a pipeline, CMOS Analog-to-Digital (A/D) con-

verter that operates from a single +5V power supply. This con-

verter provides excellent performance with a single-ended input

and can be operated with

for added spurious performance. This high performance converter

includes an 8-bit quantizer, high bandwidth

● INTERNAL OR EXTERNAL REFERENCE

OPTION

differential input

● SINGLE-ENDED OR

DIFFERENTIAL ANALOG INPUT

● PROGRAMMABLE INPUT RANGE:

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.

1Vp-p /2Vp-p

● LOW POWER: 275mW

● LOW DNL: 0.35LSB

● SINGLE +5V SUPPLY OPERATION

● SSOP-20 PACKAGE

The ADS831 employs digital error correction techniques to pro-

vide excellent differential linearity for demanding imaging appli-

cations. Its low distortion and high SNR give the extra margin

needed for medical imaging, communications, video, and test

instrumentation.

APPLICATIONS

● MEDICAL IMAGING

The ADS831 is specified at a maximum sampling frequency of

80MHz and a single-ended input range of 1.5V to 3.5V. The

ADS831 is available in an SSOP-20 package and is pin-for-pin

compatible with the 8-bit, 60MHz ADS830.

● VIDEO DIGITIZING

● COMPUTER SCANNERS

● COMMUNICATIONS

● DISK-DRIVE CONTROL
