Preliminary
1) Using Internal Resistors, Ra and Rb (INTRS =
“
H
”
)
When INTRS pin is high, resistor Ra is connected internally between VR pin and VSS, and Rb is connected
between V0 and VR. We determine V0 by two instructions,
“
Regulator Resistor Select
”
and
“
Set Reference
Voltage
”
.
Figure 11. shows V0 voltage measured by adjusting internal regulator register ratio(Rb/Ra) and 6-bit electronic
volume registers for each temperature coefficient at Ta = 25
°
C.
