The AT84AS004 10-bit 2 Gsps ADC with 1:2/4 DMUX is an upgrade of the AT84AS003 10-bit 1.5 Gsps ADC with 1:2/4 DMUX to allow users to work at 2 Gsps sampling frequency. AT84AS004 is the first ADC on the marketAT84AS004VTP_RV_AT30990 breaking the 8.0 ENOB barrier at sampling rates over 1 Gsps. At Nyquist conditions, performance such as 7.8 ENOB and 55 dB SFDR at 2 Gsps has been demonstrated. Furthermore, the 3 GHz analog input bandwidth allows operation in second Nyquist zone with remarkable performance at up to 1.5 GHz input frequency, making it a fully functional broadband analog data converter.

The embedded selectable 1:2 or 1:4 demultiplexer allows direct interfacing with standard LVDS compatible FPGAs, without any timing or voltage tuning necessary, even when sweeping the sampling frequency from 100 Msps to 2 Gsps.

It is the best option to upgrade existing systems or to design new state-of-the-art digitizers in applications such as digital receivers, test instrumentation or radar equipment.
