Description
Supply Voltage, 4.5 V to 5.5 V. This is the supply voltage for the isolated side of the AD7401A 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 MCLKIN input and valid on the following MCLKIN rising edge.
Master Clock Logic Input. 20 MHz maximum. The bit stream from the modulator is valid on the rising edge of MCLKIN.
Supply Voltage. 3 V to 5.5 V. This is the supply voltage for the nonisolated side and is relative to GND
