TI Fastest 12-bit ADC Provides Unmatched Dynamic Performance for Input Frequencies Above 500 MHz


Texas Instruments Incorporated has 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
