Fastest 12-bit ADC provides unmatched dynamic performance for input frequencies above 500 MHz

Feb 26, 2009

DALLAS (Feb. 26, 2009) - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a monolithic 12-bit, 550-MSPS (mega samples per second) analog-to-digital converter (ADC), which provides more than 200 MHz of signal bandwidth in applications where high resolution, accuracy and linearity are critical. The new pipeline ADC offers the highest spurious-free dynamic range (SFDR) and signal-to-noise ratio (SNR) available for input frequencies (IF) above 500 MHz, enabling more efficient power amplifier linearization in digital pre-distortion (DPD) solutions, better range and sensitivity in defense imaging and communication systems, and higher accuracy in wide-band test and measurement equipment.

Key Features

  • Highest linearity and SNR available above 500 MHz IF
    • 64.1 dBFS SNR, 80 dBc SFDR @ 450MHz, 500MSPS
    • 62.5 dBFS SNR, 70 dBc SFDR @ 900MHz, 500MSPS
  • Fully buffered differential analog input
  • Built in TI's BiCom3 technology

Key Benefits

  • Allows for high IF and direct RF sampling architectures to simplify system design
  • Eases analog front-end design by providing constant input impedance over input frequency and eliminating track-and-hold kick back
  • >Works well in high temperature and high radiation environments

Availability and pricing

The ADS54R463 is available today in a 14 x 14 mm TQFP package which is pin compatible to the ADS5463 and ADS5474. The device is priced at $175 in 1000-piece quantitiesFind out more about TI's high-speed data converters at the links below:.
