MSP430F5437A: ADC ENOB or SINAD

Hi TISL,

Please refer to the following E2E thread: e2e.ti.com/.../107625

The MSP430FR4133 has an ADC, not a sigma-delta A/D converter, therefore ENOB does not heavily rely on the gain and oversampling ratio. Instead it depends on the system's SNR/SINAD, which can be obtained from dynamic FFT testing. Please refer to the following App Reports, which supply useful SINAD/ENOB equations also show how oversampling in firmware can be implemented to increase the MCU's ENOB:
