Texas Instruments ADS5294IPFPT

Description
The ADS5294 is an 8-channel, 14-bit, 80 MSPS analog-to-digital converter (ADC) that combines low power consumption, high signal-to-noise ratio (SNR), low spurious-free dynamic range (SFDR), and consistent overload recovery. It features a digital processing block that includes programmable FIR decimation filters, an IIR high-pass filter, and programmable digital gain. The device also offers flexible serialized LVDS outputs, internal and external references, and low-frequency noise suppression.

75.5 dBFS SNR at 5 MHz/80 MSPS
78.2 dBFS SNR at 5 MHz/80 MSPS with decimation filter enabled
Low SFDR: 84 dBc at 5 MHz/80 MSPS
Low power consumption:
58 mW/CH at 50 MSPS
77 mW/CH at 80 MSPS (2-LVDS wire per channel)
Programmable FIR decimation filter and oversampling to minimize harmonic interference
Programmable IIR high-pass filter to minimize DC offset
