Description
Supply Voltage, 5 V ±10%. This is the supply voltage for the isolated side of the
AD7400/AD7401 and is relative to GND
1
.
Positive analog Input, range of ±200 mV .
Negative analog input (normally connected to GND
1
).
Master Clock. Logic Input. An external clock is applied at this pin. A serial clock input from
1MHz to 20MHz may be applied to this pin on the AD7401. The bit stream form the
modultaor is valid on the rising edge of MCLKIN.
Master Clock. Logic Output, 10MHz typical. The bit stream form the modultaor is valid on the
rising edge of MCLKOUT on the AD7400.
Supply Voltage, 5 V ±10% or 3V ±10%. This is the supply voltage for the non-isolated side of
the AD7400/AD7401 and is relative to GND
2
.
Ground. This is the ground reference point for all circuitry on the isolated side of the
AD7400/AD7401.
Ground. This is the ground reference point for all circuitry on the non-isolated side of the
AD7400/AD7401.
