THS3491DDA evaluation module


Order now


The THS3491DDA evaluation module (EVM) is used to evaluate the THS3491 device, which is a highspeed, high-voltage and low-distortion current-feedback amplifier in an 8-pin DDA package. The EVM is designed to quickly and easily demonstrate the functionality and performance of THS3491 in a gain of 5 V/V, driving an equivalent RLOAD = 100 Ω. The EVM is ready to connect to power supplies, signal source, and test instruments through the use of onboard connectors. The board is setup for single-ended input and output operation for interfacing with 50-Ω test equipment.

  • Configured for split-supply operation and easily modified for single supply
  • Designed for single-ended 50-Ω input and output connection
  • Configured for non-inverting gain of 5 V/V configuration and easily modified for inverting gain configuration
  • Simple interface to the inputs and outputs through the SMA connectors
  • Heat-sink on the bottom of the board to help with the overall device thermal dissipation for high output voltage swings
