SPDS105B
SPDS105B offers output DSP. Three modes include Push-Pull, Double- Double-end Single-pin Single-end. addition, also provides pair converters audio output that also input through DSP.
(REAL TIME CLOCK) Some applications require real time clock time tracking. SPDS105B provides eight sources: 2Hz, 1second, 2-second, 10-second, 30-second, 1-minute, 2-minute 4-minute. sources used time counting system awaking. Each occurs, system wakes users this signal time counting. addition, SPDS105B supports 32768 strong mode auto mode. With strong mode, 32768 always runs highest power. With auto mode, first 2-second strong mode then switch weak mode save power.
