1.3 Jumper Settings
Together with the TAS5100/TAS5110/TAS5182 PWM output stages from
Texas Instruments, the TAS5026REF module can be configured in
autorecovery mode (closed loop). The SHUTDOWN signal(s) from the output
stage is connected to error recovery at the PWM processor when JMP120 and
JMP121 are shorted.
The autorecovery loop has to be disabled when the modulator board is
connected to an output stage module with autorecovery on-chip (e.g. the
TAS5111 and the TAS5112 reference modules). Autorecovery is disabled
when JMP120 and JMP 121 are removed.
