Description

  • Circuit is a simplified diagram of a 14-bit, 125 MSPS quad ADC system that uses post digital summation to increase the signal-to-noise ratio (SNR) from 74 dBFS for a single ADC to 78.5 dBFS for the quad ADC with summation. This technique is especially suitable for applications requiring high SNR such as ultrasound and radar and makes use of modern high performance low power quad pipelined ADCs

Key Features

  • ADC Resolution
    14 Bit
  • ADC Sampling Rate
    125M SPS
  • Number of Channels
    4CH
