APPLICATION INFORMATION (continued)
Figure 25 is a reference schematic that provides TTL-level control of the M/SB terminal. A diode network is also
included which helps reduce turn-on pop noises. The diodes serve to drain the charge out of the output coupling
capacitors while the amplifier is in shutdown mode. When the M/SB voltage is in the normal operating range, the
diodes have no effect on the ac performance of the system.
A.
When S1 is closed, the depop circuitry is active during standby mode.
B.
When S2 is open, activating S1 places the TPA1517 in mute mode. When S2 is closed, activating S1 places the
TPA1517 in standby mode.
C.
The terminal numbers are for the 20-pin NE package.
