Fast 12-bit ADC meets the demands of tomorrow’s test and measurement

24-05-2019 | Texas Instruments | Semiconductors

Texas Instruments has introduced a new ultra-high-speed ADC with what is claimed to be the industry’s widest bandwidth, fastest sampling rate and lowest power consumption. The ADC12DJ5200RF assists engineers deliver high measurement accuracy for 5G testing applications and oscilloscopes, and direct X-band sampling for radar applications.

At 8GHz, the device aids engineers to deliver as much as 20% higher analog input bandwidth than competing devices, which gives engineers the capability to directly digitise very high frequencies without the power consumption, cost and size of additional down-conversion.

The device offers the highest achievable dynamic performance over power-supply variations, even at minimum specifications, which increases signal intelligence by offering ultra-high receiver sensitivity to identify even the smallest and weakest signals. Also, the device comprises internal dither, which enhances spurious-free performance.

At 10mm x 10mm – a claimed 30% smaller than discrete solutions – the device assists engineers in saving board space. This new ultra-high-speed ADC also needs a decreased number of lanes, which additionally provides for a smaller PCB design.

The device is pin-compatible with the following other TI GSPS ADCs to give a simple upgrade path from 2.7 GSPS to 10.4 GSPS and minimises the time and cost of redesign: ADC12DJ3200, ADC12DJ2700 and ADC08DJ3200.
