8.2 Typical Application
Figure 8-4 shows isolated I2C data acquisition system built with TI microcontroller, analog-to-digital converter, and I2C isolator, ISO1541-Q1.
The entire circuit operates from a single 3.3-V supply. A low-power push-pull converter, SN6501-Q1, drives a center-tapped transformer with an output that is rectified and linearly regulated to provide a stable 5-V supply for the data converter.
