TEST EQUIPMENT
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 dissipation
to only 20mW.
The ADS823 and ADS826 are specified at a maximum sam-
pling frequency of 60MHz and a single-ended input range of
1.5V to 3.5V. The ADS823 and ADS826 are available in a
28-lead SSOP package and are pin-compatible with the 10-bit,
40MHz ADS822 and ADS825, and the 10-bit, 70MHz ADS824.

DESCRIPTION
The ADS823 and ADS826 are pipeline, CMOS analog-to-
digital converters that operate from a single +5V power supply.
These converters provide excellent performance with a single-
ended input and can be operated with a differential input for
added spurious performance. These high-performance convert-
ers include a 10-bit quantizer, high-bandwidth track-and-hold,
and a high-accuracy internal reference. They also allow for
disabling the internal reference and utilizing external refer-
ences. 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.
