Music Sensor Time Constant 1. Sensing no signal to signal (Attack) is determined by C1, 0.01 µF to 1 µF capacitor C1 can be applicable. 2. Sensing signal to no signal (Recovery) is determined by C1 and R1, however preceding (1), 100 kΩ to 1 MΩ can be applicable. Music Sensor Output (MS(OUT)) As for the internal circuit of music sensor block, music sensor output pin is connected to the collector of NPN type directly, therefore, output level will be “high” when sensing no signal. And output level will be “low” when sensing signal. IL = DVCC − MS(OUT)LO* RL * MS(OUT)LO : Sensing signal (about 1V) Note: Supply voltage of MS(OUT) pin must be less than VCC voltage. 12 HA12231FP Characteristic Curves EQOUT Noise Output vs. Transmission Frequency 0 EQOUT Noise Output (dBs) −10 EQOUT(L), VCC = 9 V, Vin = 0 dBm, 120 µs FIN(L) RIN(L) toward Cellular phone noise −20 −30 −40 −50 −60 100 1000 Transmission Frequency (MHz) 10000 EQOUT Noise Output vs. Transmission Signal Input Level 0 EQOUT Noise Output (dBs) −10 −20 EQOUT(L), VCC = 9 V, 120 µs, f = 900 MHz FIN(L) RIN(L) toward Cellular phone noise −30 −40 −50 −60 −70 −80 −50 −40 −30 −20 −10 0 High Frequency Input Vin (dBm) 10 20 13 HA12231FP Quiescent Current vs. Supply Voltage 7.0 No signal 70 µ Quiescent Current (mA) 6.5 6.0 5.5 5.0 4.5 4.0 4 6 8 10 Supply Voltage (V) 12 14 16 Input Amp.
