Texas Instruments Incorporated (TI) announced the industry s best noise performance with minimum power consumption of 80MSPS, 8-channel 14-bit ADC (ADC). The ADS5294 can be 5MHz to support 75.5dBFS best signal to noise ratio (SNR), the sampling rates up to 80MSPS, fully meet the designer of the high power efficiency and low cost designs. ADS5294 at 80MSPS and can provide high performance under 77mW per channel, the lowest power consumption, integrated digital processing block, low-frequency noise suppression mode, and programmable input to output mapping function. All of these features can help the designer in a smaller package to integrate more features to the development of smaller medical imaging systems.
Key features and benefits
Industry-leading low-power low-noise performance: ADS5294 provides best-of SNR, can help designers of high-density applications without increasing power consumption in case of increased number of channels;
5MHz/80MSPS when the SNR is 75.5dBFS
5MHz and the decimation filter is enabled when the SNR is 78.2dBFS
SFDR of 84dBc at 5MHz/80MSPS
Under the power per channel 80MSPS 77mW (two per channel LVDS line)
Low-frequency noise suppression mode
Digital processing blocks integrated system of several commonly used functions, such as 2, 4 or 8 filter with dual-channel or 4 channel average or extraction function;
Digital processing block can be used to greatly enhance the SNR and harmonic filters, narrow-band applications, while reducing the output data rate;
Dual LVDS interface: The ADS5294, the digital data available for each single or dual channel LVDS output pins to reduce the number of interface lines. This will create a two-wire interface, serial data rates to maintain low to enable designers to use low-cost FPGA;
In addition to medical imaging systems outside, ADS5294 also for radar, communications, test and measurement, and other multi-channel data acquisition applications bring the same advantages.
