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
