MSB ADJUSTMENT CIRCUITRY
With the optional bit adjustment circuitry shown in Figure
4, even greater performance can be realized by reducing the
first four major bit carry output errors to zero. The most
important adjustment for low level outputs would be the step
between BPZ (bipolar zero; MSB on, all other bits off) and
the code, which is one LSB less than BPZ (MSB off, all
other bits on), since every crossing of zero would go through
this bipolar major carry point. This MSB bit adjustment would
be made by outputing a very low level signal sine wave and
calibrating the 100k
potentiometer circuit connected to P28
and P27 while monitoring the THD+N of the PCM58P until
peak performance is observed.
Bits 2 through 4 can also be adjusted if desired to obtain
optimum full-scale output THD+N performance. An addi-
tional 100k
potentiometer adjustment circuit is required for
every additional bit to be adjusted. If bit adjustment is not
performed, the respective pins on the PCM58P should be
left open.
Once bit adjustment is performed, the reference voltage at
VPOT (P28) will track the internal reference, insuring that
the THD+N performance of the PCM58P will remain unaf-
fected by external temperature changes.
