Isolated I²S Using IL710/IL711

Isolating a CD transport DAC with an isolated Inter-IC Sound (I²S) bus

eliminates ground loops. The IL700-Series isolators’ precision edge

placement (just 100 ps jitter) all but eliminates noise-induced phase error

and hum in the analog side of the audio system.

Intelligent DC-DC Converter With Synchronous Rectification

A typical primary-side controller uses an IL711 to drive the synchronous rectification signals

from primary side to secondary side. Isolator pulse-width distortion as low as 0.3 ns minimizes

MOSFET dead time and maximizes conversion efficiency.
