7.3 Feature Description

The TRF1305x1 includes the following key features:

  • Two-rail floating supply with supply-independent thermal pad
    • Connect the thermal pad to GND or VS–
    • RF signals and PD pin are referenced to thermal pad
  • Single-supply or split-supply operation
  • Supports single-ended and differential input configurations
  • Performance-optimized preset fixed-gain variants
  • Output common-mode control
  • Input common-mode range selection by pullup resistor
  • MODE pin: VICM range extension closer to VS+ or VS– modes
  • Digital-logic-controllable power-down option
