TI ADS5294 14-bit, 8-channel ADC Offers Great Noise Performance and Low Power

Texas Instruments recently introduced their ADS5294 analog to digital converter. The TI ADC features the best noise performance and lowest power octal-channel in a 14-bit ADC at 80 MSPS. The Texas Instruments ADS5294 ADC is available now in a 12-mm x 12-mm, 80-pin QFP package. It is is priced at $84 (quantities of 1,000). The TI ADS5294 analog to digital converter is ideal for medical imaging, radar, communications, test and measurement and other multi-channel data acquisition applications.

The ADS5294 ADC features a signal-to-noise ratio (SNR) of 75.5 dBFS at 5 MHz, sampling frequency of up to 80 MSPS, and power consumption of 77 mW per channel at 80 MSPS. The new analog to digital converter also integrates a digital processing block, a low-frequency noise suppression mode and programmable input-to-output mapping. As a result, system designers can integrate more functions in a smaller footprint and create more compact medical imaging systems.

Texas Instruments ADS5294 Analog to Digital Converter Features

  • 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
  • Eight input channels
  • Typical power consumption 464mW
  • Digital processing block integrates commonly used system functions such as two- or four-channel averaging and decimation by two, four or eight filters
  • Digital processing block improves SNR and filter harmonics, and reduces output data rate for narrow-band applications
  • Digital data can be output over one or two wires of LVDS pins per channel reducing the number of interface lines
  • Two-wire interface keeps the serial data rate low and enables designers to use low cost FPGA devices
  • Ideal for medical imaging, radar, communications, test and measurement and other multi-channel data acquisition applications
