POWERING UP THE AD7298-1
The AD7298-1 contains a power-on reset circuit that sets the
control register to its default setting of all zeros; therefore, the
internal reference is enabled and the device is configured for the
normal mode of operation. At power-up, the internal reference is
by default enabled, which takes up to 6 ms (maximum) to power up.
If an external reference is being used, the user does not need to
wait for the internal reference to power up fully. The AD7298-1
digital interface is fully functional after 500 s from the initial
power-up. Therefore, the user can write to the control register
after 500 s to switch to external reference mode. The AD7298-1 is
then immediately ready to convert once the external reference is
available on the VREF pin.
When supplies are first applied to the AD7298-1, the user must
wait the specified 500 s before programming the control register
to select the desired channels for conversion.
RESET
The AD7298-1 includes a reset feature that can be used to reset
the device and the contents of all internal registers, including
the control register, to their default state.
To activate the reset operation, the PD/RST pin should be brought
low for no longer than 100 ns. It is asynchronous with the clock;
therefore, it can be triggered at any time. If the PD/RST pin is
held low for greater than 100 ns, the part enters full power-down
mode. It is imperative that the PD/RST pin be held at a stable
logic level at all times to ensure normal operation.
