The D is set to a particular level among the 64 possible levels through the use of the
electronic volume function, depending on the data set in the 6-bit electronic volume
register. The left table below shows the value for D, depending on the electronic
volume register settings.
Rb/Ra is the V
levels through the V
(1+Rb/Ra) ratio assumes the values shown in the right table below, depending on the
3-bit data settings in the V
The VREG is affected by Temperature interference, which is cause by a semiconductor
material character. The Temperature coefficient is about –0.3% / °C.
