Optimizing THS4509 to Drive High Speed ADCs Reference Design

Overview

TopologyOther Topology
IC revisionB

Description

This reference design shows the ability of the high-speed amplifier, THS4509 to perform single-ended to differential conversion to drive high-speed analog-to-digital converters (ADCs) while maintaining excellent noise and distortion performance. Performance versus input frequency is shown for both AC and DC coupled applications while interfaced to the ADS4449 quad, 250-MSPS, 14-bit ADC. Various options for common-mode voltages, power supplies, and interfaces are discussed and measured to meet the requirements of a variety of applications. Anti-aliasing filter examples are shown along with the performance improvements that they provide.

Features

  • High-speed single-ended to differential conversion while maintain excellent performance
  • System performance results for THS4509 driving ADS4449
  • SFDR > 77 dBFs, SNR > 71 dBFS in first Nyquist zone
  • SFDR > 69 dBFs, SNR > 67 dBFS in second Nyquist zone
  • Examples of both AC and DC coupled interfaces
  • Demonstrates anti-aliasing filter design and performance gains
  • Amplifier power supply design considerations for best performance are discussed
