ADS5203 General Description
The ADS5203 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 3.3V TTL/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.
he ADS5203 is characterized for operation from 40°C to +85°C and is available in a TQFP-48 package.
