TI offers best noise performance and lowest power in 14-bit, 8-channel ADC at 80 MSPS for medical imaging applications

Key features and benefits
Leading noise and power performance: The ADS5294 provides best-in-class SNR and enables designers of high-density applications to increase channel count without increasing power.
75.5 dBFS SNR at 5 MHz/80 MSPS
78.2 dBFS SNR at 5 MHz and decimation filter enabled
84 dBc SFDR at 5 MHz/80 MSPS
77 mW per channel at 80 MSPS (two LVDS wires per channel)
Low-frequency noise suppression mode.
Digital processing block that 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 significantly improve SNR and filter harmonics, while reducing output data rate for narrow-band applications.
Two-wire LVDS interface: 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.
