The ADS5204 is a dual 10-bit, 40MSPS Analog-to-Digital
Converter (ADC). It simultaneously converts each analog
input signal into a 10-bit, binary coded digital word up to
a maximum sampling rate of 40MSPS per channel. All
digital inputs and outputs are 3.3VTTL/CMOS compatible.
An innovative dual pipeline architecture implemented in
a CMOS process and the 3.3V supply results in very low
power dissipation. In order to provide maximum flexibility,
both top and bottom voltage references can be set
from user-supplied voltages. Alternatively, if no external
references are available, the on-chip internal references
can be used. Both ADCs share a common reference
to improve offset and gain matching. If external
reference voltage levels are available, the internal references
can be powered down independently from the
rest of the chip, resulting in even greater power savings.
The ADS5204 also features dual, onboard Programmable
Gain Amplifiers (PGAs) that allow a setting of 0dB to 18dB
to adjust the gain of each set of inputs in order to match
the amplitude of the incoming signal.
The ADS5204 is characterized for operation from –40°C
to +85°C and is available in a TQFP-48 package.
