ADuM7703 - Analog Devices

ADuM7703 Sigma-Delta ADC

The ADuM7703 is a high performance, second-order, Σ-Δ analogto-digital converter (ADC) with an integrated low dropout (LDO) regulator that converts an analog input signal into a high speed, single-bit data stream with on-chip digital isolation based on Analog Devices, Inc., iCoupler® technology. The device operates from a 4.5 V to 20 V power supply range (VD.
