Description

The ISOSD61 is a galvanic isolated second order Sigma-Delta modulator based on

embedded transformer coupling technology. It converts an analog input signal with

maximum range of ±320 mV into a high speed, 25 Msps, 1-bit digital data stream.

The signal information can be rebuilt by means of a digital filtering. The modulator is

isolated from the digital I/O section through a high-speed isolated data coupling,

whose performances are far better than other isolated transceivers like optocouplers.
