SLS System Logic Semiconductor
In Case of Using Internal Resistors, Ra and Rb (INTRS = “H”)
V0 and VR. We determine V0 by two instructions, “Regulator Resistor Select” and “Set Reference Voltage”.
Table 11. Internal Rb/Ra ratio depending on 3-bit data (R2 R1 R0)
electronic volume registers for each temperature coefficient at Ta = 25
Figure 11. Electronic Volume Level
When INTRS pin is “H”, resistor Ra is connected internally between VR pin and VSS, and Rb is connected between
The following figure shows V0 voltage measured by adjusting internal regulator resistor ratio (Rb/Ra) and 6-bit
