DESCRIPTION

The ADS823 and ADS826 are pipeline, CMOS Analog-to-

Digital Converters (ADCs) that operate from a single +5V

power supply. These converters provide excellent perfor-

mance with a single-ended input and can be operated with a

differential input for added spurious performance. These

high-performance converters include a 10-bit quantizer, high-

bandwidth track-and-hold, and a high-accuracy internal ref-

erence. They also allow for disabling the internal reference

and utilizing external references. This external reference

option provides excellent gain and offset matching when

used in multi-channel applications or in applications where

full-scale range adjustment is required.

Int/Ext

The ADS823 and ADS826 employ digital error correction

techniques to provide excellent differential linearity for de-

manding imaging applications. Their low distortion and high

SNR give the extra margin needed for medical imaging,

communications, video, and test instrumentation. The ADS823

and ADS826 offer power dissipation of 265mW and also

provide a power-down mode, thus reducing power dissipa-

tion to only 20mW.

The ADS823 and ADS826 are specified at a maximum

sampling frequency of 60MHz and a single-ended input

range of 1.5V to 3.5V. The ADS823 and ADS826 are avail-

able in an SSOP-28 package and are pin-compatible with the

10-bit, 40MHz ADS822 and ADS825, and the 10-bit, 75MHz

ADS828.
