14-bit, 8-channel ADC offers best noise performance and lowest power at 80 MSPS for medical imaging applications
Along with high performance and lowest power consumption of 77 mW per channel at 80 MSPS, ADS5294 also integrates a digital processing block, a low-frequency noise suppression mode and programmable input-to-output mapping. All the features allow system designers to integrate more functions in a smaller footprint, resulting in more compact medical imaging systems.
The device’s digital processing block integrates several commonly used system functions such as two- or four-channel averaging and decimation by two, four or eight filters. The digital processing block can be used to improve SNR and filter harmonics, while reducing output data rate for narrow-band applications.
Using the ADS5294, digital data can be output over one or two wires of LVDS pins per channel reducing the number of interface lines. This creates a two-wire interface which keeps the serial data rate low allowing designers to use low cost FPGAs.
In addition to medical imaging systems, the ADS5294 brings the same benefits to radar, communications, test and measurement and other multi-channel data acquisition applications.
To provide a flexible environment for testing the ADS5294 under a variety of conditions, an evaluation module (EVM) is available. The ADS5294 EVM is priced at $299 and can be found at www.ti.com/ads5294evm-pr
Availability and Packaging
The ADS5294 is available now in a 12-mm x 12-mm, 80-pin QFP package. The ADS5294 is priced at $84 in quantities of 1,000.
