Industry’s Fastest 12-bit ADC Races to 4 GSPS

Thu, 02/20/2014 - 4:54pm

Texas Instruments (TI) (Dallas, TX) introduced the industry’s fastest 12-bit analog-to-digital converter (ADC). The RF-sampling ADC12J4000 clocks in at 4 GSPS and supports the JEDEC JESD204B serial interface standard for data converters up to 8 Gbps, while consuming 50 percent less power than competitive devices. Measuring 10-mm by 10-mm, it is also the smallest IC in its class. The ADC12J4000 can be used in test and measurement, wireless, and defense applications, such as spectrum analyzers, munitions, digital pre-distortion feedback and radar. Key benefits include:

  • Wideband sampling: Provides RF sampling capabilities with more than 3-GHz input bandwidth.
  • Lowest power consumption: Consumes only 1.9 W of power, 50 percent less than competitive devices.
  • Flexible signal bandwidth: Provides a low-noise power ratio of 48.5 dB and noise floor of -149 dBFS/Hz, along with high linearity for signals up to and beyond intermediate frequencies of 3 GHz. These features enable system designs to sample at higher frequencies.
  • RF-sampling analog front-end: The pin-compatible, 4-GSPS, ultra-wideband, RF-sampling LM15851 analog front end (AFE) is export license free.
