The ADS822 and ADS825 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 converters in-
clude a 10-bit quantizer, high-bandwidth track-and-hold, and a
high-accuracy internal reference. They also allow 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 applica-
tions where full-scale range adjustment is required.
The ADS822 and ADS825 employ digital error correction tech-
niques 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 ADS822 and ADS825 offer
power dissipation of 190mW and also provide a power-down
mode, thus reducing power dissipation to only 20mW. The
ADS825 is +3V or +5V Logic I/O compatible.
The ADS822 and ADS825 are specified at a maximum sampling
frequency of 40MHz and a single-ended input range of 1.5V to
3.5V. The ADS822 and ADS825 are available in a 28-lead SSOP
package and are pin-for-pin compatible with the 10-bit, 60MHz
ADS823 and ADS826, and the 10-bit, 70MHz ADS824, provid-
ing an upgrade path to higher sampling frequencies.
