Fastest 14-bit ADC enables high-bandwidth apps

400-Msample/s part provides 11.1 ENOB

Claimed to be the industry’s fastest monolithic 14-bit A/D converter at 400 Msamples/s, the ADS5474 provides 11.1 effective number of bits (ENOB)—enabling high-bandwidth applications such as test and measurement instrumentation, software-defined radio, radar systems, and communication instrumentation that were previously confined to lesser-resolution ADCs. Using the company’s BiCom3 process technology, the part integrates an on-chip buffer amplifier, which eases analog front-end design by eliminating sample-and-hold kickback.

Features include a 70-dBFS SNR through first Nyquist and 69-dBFS SNR through second Nyquist. The ADS5474 is available now in an 80-pin TQFP PowerPAD package and is pin-for-pin compatible to the ADS5463 12-bit 500-Msample/s A/D converter. ($150 ea/1,000—samples available now.)
