Exploring TIC digital interface
This application report presents a TIC Digital Interface, which considers an early analog-to-digital conversion with the help of a ΔΣ-modulator AMC1204 device and, for data processing, a MSP430 microcontroller. Out of the analog TIC signal, the AMC1204 device generates a bit stream, which is used as clock input for a MSP430 timer module. A transmitted logical "1" leads to a slow-counting frequency, whereas a "0" leads to a fast-counting frequency. The sampled data is forwarded to the application with a distinction between cases and a synchronization clock of the MSP430.
Due to its simple design and the internal isolation of the AMC1204 device, the TIC Digital Interface does not require a transformer in the signal path, unlike analog solutions, which require a transformer.
