Supply Voltage Range
Product 7.2 V to 12.0 V Single Supply
Reference Voltage HA12231FP provides the reference voltage of half the supply voltage that is the signal grounds. As the peculiarity of this device, the capacitor for the ripple filter is very small about 1/100 compared with their usual value. The block diagram is shown as figure 1.

Notes: 1. Each pins are on pulled down with 100 k internal resistor. Therefore, it will be low-level when each pins are open. 2. Over shoot level and under shoot level of input signal must be the standardized. (High: VCC, Low: -0.2 V) 3. Reducing pop noise is so much better for 10 k to 22 k resisitor and 1 F to 22 F capacitor shown figure 2.

The sensitivity of music sensor (S) is computed by the formula mentioned below.
S = 12.7 - GV [dB]
S is 6 dB down in case of one-side channel. Notes: 1. Search mode: GV1, Repeat mode: G V2 2. Standard level of TAI pin (Dolby level correspondence) = 30 mVrms 3. Standard sensing level of music sensor = 130 mVrms

Music Sensor Time Constant 1. 2. Sensing no signal to signal (Attack) is determined by C1, 0.01 F to 1 F capacitor C1 can be applicable. Sensing signal to no signal (Recovery) is determined by C1 and R1, however preceding (1), 100 k to 1 M 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.
