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.
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.
