OPERATING MODES
The AD7816, AD7817, and AD7818 have two possible modes
of operation depending on the state of the
CONVST
pulse at
the end of a conversion.
Mode 1
In this mode of operation the
CONVST
pulse is brought high
before the end of a conversion, i.e., before the BUSY goes low
(see Figure 16). When operating in this mode a new conversion
should not be initiated until 100 ns after the end of a serial read
operation. This quiet time is to allow the track/hold to accu-
rately acquire the input signal after a serial read.
Mode 2
When the AD7816, AD7817, and AD7818 are operated in Mode
2 (see Figure 17), they automatically power down at the end of
a conversion. The
CONVST
is brought low to initiate a conver-
sion and is left logic low until after the end of the conversion. At
this point, i.e., when BUSY goes low, the devices will power-
down. The devices are powered up again on the rising edge of
the
CONVST
signal. Superior power performance can be
achieved in this mode of operation by powering up the AD7816,
AD7817, and AD7818 only to carry out a conversion (see Power
vs. Throughput section). In Figure 17 the
CS
line is applicable
to the AD7817 only.
