Texas Instruments ADS5294 Octal Channel 14-Bit, 80MSPS ADC

TI ADS5294 Octal Channel 14-Bit, 80MSPS ADC

Texas Instruments ADS5294 Octal Channel 14-Bit, 80MSPS analog-to-digital converter (ADC) provides low power consumption, high SNR, low SFDR, and consistent overload recovery, allowing users to design high performance systems. TI 8-channel ADS5294 ADC has a digital processing block that integrates several commonly used digital functions for improving system performance. The device includes a digital filter module that has built-in decimation filters (with low-pass, high-pass and band-pass characteristics). The decimation rate is also programmable (by 2, 4, or 8). This makes it useful for narrow-band applications, where the filters can be used conveniently to improve SNR and knock-off harmonics while also reducing the output data rate.
