Description

VDD1

Supply Voltage, 4.5 V to 20 V. This pin is the supply voltage for the isolated side of the ADuM7703 and is relative to

GND1. For device operation, connect the VDD1 supply voltage to the VDD1 pin. Decouple the supply pin to GND1 with

a 10 μF capacitor in parallel with a 100 nF capacitor as close to the pin as possible.

VIN+

Positive Analog Input.

VIN−

Negative Analog Input.

GND1

Ground 1. This pin is the ground reference point for all circuitry on the isolated side.

GND2

Ground 2. This pin is the ground reference point for all circuitry on the nonisolated side.

MDAT

Serial Data Output. The single-bit modulator output is supplied to this pin as a serial data stream. The bits are

clocked out on the rising edge of the MCLKIN input and are valid on the following MCLKIN rising edge.

MCLKIN

Master Clock Logic Input, 5 MHz to 21 MHz frequency range. The bit stream from the modulator is propagated on

the rising edge of the MCLKIN.

VDD2

Supply Voltage, 3 V or 5.5 V. This pin is the supply voltage for the nonisolated side and is relative to GND2.

Decouple this supply to GND2 with a 10 μF capacitor in parallel with a 100 nF capacitor as close to the pin as possible.
