Analog current and voltage output drivers are used to signal 4-20mA current signals or -10V to 10V voltage signals per IEC 61131-2 Industrial process standard. ISOMOS can be employed to achieve output isolation and glitch-free power ups as illustrated in Figure 2-2.

In a normal use case, while forcing analog signals either voltage or current, ISOMOS is enabled by setting V_{EN_SW} = High to establish the path to the load, thereby closing the signal path to load for communication. ISOM8610 supports 150mA on state current, sufficient for analog output signaling.

During scenarios where Drive (DRV) output is disabled, the output for Analog output IC gets tri-stated. Any small change in the driver input couples to the analog output line, sending across an unintended signal to the load. During these scenarios, ISOMOS can be used to truly isolate the load by simply turning off the LED emulator input by setting V_{EN_SW} = Low. ISOMOS output stage when OFF has a blocking voltage of 70V, which can easily support the signal common mode in analog output modules.

Additionally, ISOM8610 supports 3750Vrms isolation rating, an excellent choice for realizing analog voltage/current outputs with load isolation, with control signals on the cold side.
