Description: The ADS5204 is a dual 10-bit, 40MS...
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 compat-ible.namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
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 flexibil-ity, both top and bottom voltage references can be set from user-supplied voltages. Alternatively, if no external references are available, the on-chip internal refer-ences can be used. Both ADCs share a common refer-ence to improve offset and gain matching. If external reference voltage levels are available, the internal refer-ences 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 to +85 and is available in a TQFP-48 package.
