Description

1, 5, 7

2

Positive Analog Input.

3

Negative Analog Input.

4, 8

Ground 1. These pins are the ground reference point for all circuitry on the isolated side.

6

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

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

9, 16

Ground 2. These pins are 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.

13

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.
