STMicroelectronics ISOSD61 Sigma-Delta Modulators
STMicroelectronics ISOSD61 Sigma-Delta Modulators are based on embedded transformer coupling technology. The modulators convert an analog input signal with a maximum range of ±320mV into a high speed, 25Msps, 1-bit digital data stream. The signal information is rebuilt by means of digital filtering. The modulator is isolated from the digital I/O section through a highspeed isolated data coupling, whose performances are far better than other isolated transceivers like optocouplers.
