POWER-UP AND CALIBRATION
On power-up, the AD7707 performs an internal reset that sets
the contents of the internal registers to a known state. There are
default values loaded to all registers after power-on or reset. The
default values contain nominal calibration coefficients for the
calibration registers. However, to ensure correct calibration for
the device, a calibration routine should be performed after
power-up. A calibration should be performed if the update rate
or gain are changed.
The power dissipation and temperature drift of the AD7707 are
low and no warm-up time is required before the initial calibration
is performed. However, if an external reference is being used,
this reference must stabilize before calibration is initiated.
Similarly, if the clock source for the part is generated from a
crystal or resonator across the MCLK pins, the start-up time for
the oscillator circuit should elapse before a calibration is
initiated on the part (see the Clocking and Oscillator Circuit
section).
