Typical Application Circuit
Figure 11. Isolated I

C Data Acquisition System
In Figure 11, the ultra low-power micro controller, MSP430G2132, controls the I
2
C data traffic of configuration
data and conversion results for the analog inputs and outputs. Low-power data converters build the analog
interface to sensors and actuators. The ISO1541 provides the necessary isolation between different ground
potentials of the system controller, remote sensor, and actuator circuitry to prevent ground loop currents that
otherwise may falsify the acquired data.
The entire circuit operates from a single 3.3 V supply. A low-power push-pull converter, SN6501, drives a center-
tapped transformer whose output is rectified and linearly regulated to provide a stable 5 V supply for the data
converters.
