... This minimizes voltage glitches at the output during turn-on and turn-off, reducing audible noise on activation and deactivation. The default gain of the SSM2319 is 12 dB, but users can reduce the gain by using a pair of external resistors (see the Gain section). The SSM2319 is specified over the industrial temperature range of − ...

... SSM2319 amplifiers. The SSM2319 also offers protection circuits for overcurrent and temperature protection. GAIN The SSM2319 has a default gain that can be reduced by using a pair of external resistors with a value calculated as follows: External Gain Settings = 160 kΩ/(40 kΩ POP-AND-CLICK SUPPRESSION Voltage transients at the output of the audio amplifiers can occur when shutdown is activated or deactivated ...

... SSM2319 Operating Modes The SYNC operating modes include the following: • Initial SYNC startup. An internal reference signal, REF, is released after one complete internal clock cycle (MCLK). After REF is released, another internal signal, MOD, waits 127 internal clock cycles. This operates as a training signal to determine the SYNCI/SYNCO connection ...
