产品描述

The ADS5204 is a dual 10-bit, 40 MSPS 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 40 MSPS per channel. All digital inputs and outputs are 3.3-V TTL/CMOS compatible.

An innovative dual pipeline architecture implemented in a CMOS process and the 3.3-V 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 0 dB to 18 dB 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.
