Description
1, 7
VDD1
Supply Voltage, 4.5 V to 5.5 V. This is the supply voltage for the isolated side of the AD7403 and is relative to GND1.
For device operation, connect the supply voltage to both Pin 1 and Pin 7. Decouple each supply pin to GND1 with
a 10 µF capacitor in parallel with a 1 nF capacitor.
2
VIN+
Positive Analog Input.
3
VIN−
Negative Analog Input. Normally connected to GND1.
4, 8
GND1
Ground 1. This pin is the ground reference point for all circuitry on the isolated side.
5, 6
NIC
Not Internally Connected. These pins are not internally connected. Connect to VDD1, GND1, or leave floating.
9, 16
GND2
Ground 2. This pin is the ground reference point for all circuitry on the nonisolated side.
10, 12, 15
NIC
Not Internally Connected. These pins are not internally connected. Connect to VDD2, GND2, or leave floating.
11
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 20 MHz frequency range. The bit stream from the modulator is propagated on
the rising edge of the MCLKIN.
14
VDD2
Supply Voltage, 3 V to 5.5 V. This is the supply voltage for the nonisolated side and is relative to GND2. Decouple
this supply to GND2 with a 100 nF capacitor.
