6.11.14 TIA0

The Transimpedance Amplifier (TIA) is a high-performance low-power amplifier with rail-to-rail output. This module is an amplifier that converts current to voltage. It has programmable power modes: high power or low power. For more information, see the Transimpedance Amplifier (TIA) chapter in the MSP430FR4xx and MSP430FR2xx Family User's Guide.

The FR231x device in the TSSOP-16 package supports a dedicated low-leakage pad for TIA negative input to support low-leakage performance. In other packages (TSSOP-20 and VQFN-16), the TIA negative port is shared with a GPIO to support the transimpedance amplifier function. For more information, see Section 4 and Table 5-25.

The TIA supports external input (see Table 6-22 and Section 4).
