Description
Supply Voltage, 4.5 V to 5.5 V. This is the supply voltage for the isolated side of the AD7400A and
is relative to GND
Positive Analog Input. Specified range of ±250 mV.
Negative Analog Input. Normally connected to GND
No Connect.
Ground 1. This is the ground reference point for all circuitry on the isolated side.
Ground 2. This is the ground reference point for all circuitry on the nonisolated side.
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 MCLKOUT output and are valid on the following
MCLKOUT rising edge.
Master Clock Logic Output (10 MHz Typical). The bit stream from the modulator is valid on the
rising edge of MCLKOUT.
Supply Voltage, 3 V to 5.5 V. This is the supply voltage for the nonisolated side and is relative to GND
