Texas Instruments Pioneers New High-Speed ADC

Texas Instruments has pioneered a new ultra-high-speed analog-to-digital converter (ADC). TI said that the newly released ADCs have the industry’s widest bandwidth, fastest sampling rate, and lowest power consumption.

The Major Applications of the latest ADCs include:

Engineers achieve high measurement accuracy for

  • 5G testing applications
  • Oscilloscopes
  • Direct X-band sampling for radar applications

The Key Features of Texas Instruments’ New ADCs include:

  • Widest bandwidth: At 8 GHz, the ADC12DJ5200RF enables engineers to achieve as much as 20% higher analog input bandwidth than competing devices, which gives engineers the ability to directly digitize very high frequencies without the power consumption, cost and size of additional down-conversion.
  • Fastest 12-bit ADC: In dual-channel mode, the ADC12DJ5200RF samples at 5.2 gigasamples per second (GSPS) and captures instantaneous bandwidth (IBW) as high as 2.6 GHz at 12-bit resolution. In single-channel mode, the new ultra-high-speed ADC samples at 10.4 GSPS and captures IBW up to 5.2 GHz.
  • Efficient interface: As the first standalone GSPS ADC to support the JESD204C standard interface, the ADC12DJ5200RF helps minimize the number of serializer/deserializer lanes needed to output data to field-programmable gate arrays (FPGAs), enabling designers to achieve higher data rates.
  • Highest signal detection sensitivity: The ADC12DJ5200RF has the highest available dynamic performance across power-supply variations, even at minimum specifications, which improves signal intelligence by providing ultra-high receiver sensitivity to detect even the smallest and weakest signals. In addition, the device includes internal dither which improves spurious-free performance.
  • High measurement accuracy: TI’s new ultra-high-speed ADC greatly minimizes system errors with offset error as low as ±300 µV and zero temperature drift.
  • Lowest CER: Engineers designing test and measurement equipment can achieve high measurement repeatability by taking advantage of the extremely low code error rate (CER) of the ADC12DJ5200RF, which is more than 100 times better than competing devices.
  • Smaller design footprint: At 10 mm by 10 mm – 30% smaller than discrete solutions – the ADC12DJ5200RF helps engineers save board space. This new ultra-high-speed ADC also requires a reduced number of lanes, which further allows for a smaller printed circuit board design.

The ADC12DJ5200RF is pin-compatible with the following other TI GSPS ADC to provide an easy upgrade path from 2.7 GSPS to 10.4 GSPS and minimizes the time and cost of redesign: ADC12DJ3200, ADC12DJ2700, and ADC08DJ3200.

Availability and packaging

The ADC12DJ5200RF dual- and single-channel ultra-high-speed ADC is available for sampling through the TI store. The device is in a 144-ball, 10-by-10-mm flip-chip ball grid array (FCBGA) package.
