This data sheet describ
and AD7401, which are
modulators that convert an analog input signal into a high
speed, 1-bit data stream with on-chip digital isolation based
on Analog Devices Inc., iCoupler® technology. The AD7400
and AD7401 operate from a 5 V power supply and accept a
differential input signal of ±200 mV (±320 mV full scale).

The analog input is continuously sampled by the analog mod-
ulator, eliminating the need for external sample-and-hold
circuitry. The input information is contained in the output
stream as a density of ones with a data rate of 10 MHz. The
original information can be reconstructed with an appropriate
digital filter. The serial I/O can use a 5 V or a 3 V supply (V
Full details on the AD7400 and AD7401 are available in the
AD7400 and AD7401 data sheets, which are available from
Analog Devices and should be consulted in conjunction with
this data sheet when using the evaluation board.
On-board components include two
for buffering the differential analog input to the AD7400 and
AD7401. Various link options are explained in the Link Options
section. Interface to this board using a standard 2-row 34-pin
