7.4.1.1 Input Common-Mode Extension

When configured in one of the VICM extension modes, the TRF1305A2 supports a VICM voltage closer to either VS+ or VS– voltage instead of the default specified input common-mode range in the Electrical Characteristics. The VICM extension mode functions only in D2D configuration.

When configured in the low-side VICM extension mode, the TRF1305A2 supports a 350mV lower input common-mode voltage than the default option. For example, the lower limit of the VICM voltage range extends from a default value of VS– + 1.5V to VS– + 1.15V for the TRF1305A2 variant, and the higher limit also shifts lower from a default value of VS– + 3.5V to VS– + 3.15V. At the lowest VICM voltage, approximately 15mA current is sunk by the external circuitry connected to the INPx and INMx pins.

When configured in the high-side VICM extension mode, the TRF1305A2 supports a 350mV higher input common-mode voltage than the default option. For example, the higher limit of VICM voltage range extends from a default value of VS– + 3.5V to VS– + 3.85V for the TRF1305A2 variant, and the lower limit also shifts up from a default of VS– + 1.5V to VS– + 1.85V. At the highest VICM voltage, approximately 15mA current is sourced by the external circuitry connected to the INPx and INMx pins.

Use resistors connected to supplies (or external current sources) to sink currents flowing out of the INPx and INMx pins during the low-side VICM extension mode, or to source currents flowing into the INPx and INMx pins during the high-side VICM extension mode.
