AD7853/AD7853L
CONFIGURING THE AD7853/AD7853L
AD7853/AD7853L as a Read-Only ADC
The AD7853/AD7853L contains fourteen on-chip registers
which can be accessed via the serial interface. In the majority of
applications it will not be necessary to access all of these regis-
ters. Figure 38 outlines a flowchart of the sequence which is
used to configure the AD7853/AD7853L as a Read-Only ADC.
In this case there is no writing to the on-chip registers and only
the conversion result data is read from the part. Interface Mode
1 cannot be used in this case as it is necessary to write to the
control register to set Interface Mode 1. Here the CLKIN signal
is applied directly after power-on, the CLKIN signal must be
present to allow the part to perform a calibration. This auto-
matic calibration will be completed approximately 32 ms after
the AD7853 has powered up (4 MHz CLK).
