USING THE AD7765
The following is the recommended sequence for powering up
and using the AD7765:
1. Apply power to the device.
2. Apply the MCLK signal.
3. Take RESET low for a minimum of one MCLK cycle,
preferably synchronous to the falling MCLK edge. If
multiple parts are to be synchronized, apply a common
4. Wait a minimum of two MCLK cycles after
RESET to all devices.

5. If multiple parts are being synchronized, a

SYNC pulse
must be applied to the parts, preferably synchronous with
the MCLK rising edge. In the case where devices are not
being synchronized, no SYNC pulse is required; a logic
high signal should simply be applied to the SYNC
When applying the
pin.

Ensure that the

coincide with a write to the device.

Data can then be read from the device using the default gain
and overrange threshold values. The conversion data read is not
valid, however, until the settling time of the filter has elapsed.
Once this has occurred, the FILTER-SETTLE status bit is set,
indicating that the data is valid.
Values for gain and overrange thresholds can be written to or
read from the respective registers at this stage.
pulse is taken low for a
minimum of four MCLK periods.
BIAS RESISTOR SELECTION
The AD7765 requires a resistor to be connected between the
RBIAS and AGNDx pins. The resistor value should be selected to
give a current of 25 A through the resistor to ground. For a
4.096 V reference voltage, the correct resistor value is 160 k.
