ADS824
DESCRIPTION
The ADS824 is a pipeline, CMOS analog-to-digital converter
that operates from a single +5V power supply. This converter
provides excellent performance with a single-ended 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 multi-channel applications or in applications
where full scale range adjustment is required.
The ADS824 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 ADS824 offers power dissipa-
tion of 315mW and also provides a power-down mode, thus
reducing power dissipation to only 20mW.
The ADS824 is specified at a maximum sampling frequency of
70MHz and a single-ended input range of 1.5V to 3.5V. The
ADS824 is available in a 28-lead SSOP package and is pin
compatible with the 10-bit, 40MHz ADS822 and the 10-bit,
60MHz ADS823.
