250-mA high-speed buffer evaluation module


Order now


The BUF634ADRBEVM is an evaluation module (EVM) for the BUF634A high-speed buffer in the DRB (8-pin DFN) package. The BUF634ADRBEVM features two BUF634AIDRB devices and is designed to quickly demonstrate the functionality and versatility of the buffer. Optionally, the buffers can be configured as outputs for a dual SOIC amplifier in a composite loop. The EVM is ready to connect to power, signal sources, and test instruments by using onboard connectors. The default configuration uses split supplies and subminiature version A (SMA) input and output connecters with a 50-Ω output impedance for standard test equipment. The EVM can be easily configured for other connections and single-supply operation. Dual-channel path configuration is also available for the TM audio input jacks and a 3.5-mm output jack.

  • Easy evaluation with standard benchtop test equipment
  • Includes connections for audio inputs and outputs
  • Board has option to form composite loop with dual SOIC op-amp
  • Configurable for split or single supply operation
