Overview

The ADuM7703 is a high performance, second-order, Σ-Δ analog-to-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 (VDD1) and accepts a pseudo differential input signal of ±250 mV (±320 mV full-scale). The pseudo differential input is ideally suited to shunt voltage monitoring in high voltage applications where galvanic isolation is required.

The serial interface is digitally isolated. High speed complementary metal-oxide semiconductor (CMOS) technology, combined with monolithic transformer technology, results in the on-chip isolation providing outstanding performance characteristics, superior to alternatives such as optocoupler devices. The ADuM7703 device is available in a 16-lead, wide-body SOIC with an operating temperature range of −40°C to +125°C and an 8-lead, wide-body SOIC with an operating temperature range of −40°C to +105°C.
