DESCRIPTION

The ADS828 is a pipeline, CMOS analog-to-digital converter

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

converter provides excellent performance with a singleended

input and can be operated with a differential input for

added spurious performance. This high performance converter

includes a 10-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 multichannel

applications or in applications where full scale

range adjustment is required.

The ADS828 employs digital error correction techniques to

provide excellent differential linearity for demanding imaging

applications. Its low distortion and high SNR give the

extra margin needed for medical imaging, communications,

video, and test instrumentation. The ADS828 offers power

dissipation of 325mW and also provides a power-down

mode, thus reducing power dissipation to only 20mW.

The ADS828 is specified at a maximum sampling frequency

of 75MHz and a single-ended input range of 1.5V to 3.5V.

The ADS828 is available in a SSOP-28 package and is pin

compatible with the 10-bit, 40MHz ADS822 and ADS825,

and the 10-bit, 60MHz ADS823 and ADS826.
