Power Control Function
The EL1503A contains two forms of power control operation.
Two digital inputs, C0 and C1, can be used to control the
supply current of the EL1503A drive amplifiers. As the
supply current is reduced, the EL1503A will start to exhibit
slightly higher levels of distortion and the frequency
response will be limited. The 4 power modes of the EL1503A
are set up as shown in the table 2.
Another method for controlling the power consumption of the
EL1503A is to connect a resistor from the IADJ pin to ground.
When this pin is grounded (the normal state), the supply
current per channel is as per the specifications table on page
3. When a resistor is inserted, the supply current is scaled
according to the “IS vs RSET” graphs on page 10 in the
Performance Curves section.
Both methods of power control can be used simultaneously.
In this case, positive and negative supply currents (per amp)
are given by the equations below:
