ISOSD61L

ISOSD61L is a galvanic isolated second order sigma-delta modulator based on embedded transformer coupling technology. It converts an analogue input signal with maximum range of ±320mV into a high speed, 25Msps, 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. Current or voltage sensing in industrial motor control, solar inverter, UPS, electric vehicle charger and telecom and server power supply.
