6 / 16 page TA2145AFG 2006-04-19 6 Application Note • VCC and GND This IC has two VCC terminals and three GND terminals. Pattern layout should be designed carefully to reduce the common impedance. • VCC VCC (pin 17) ---------------- Preamplifier stage and power amplifier stage. GVN VCC (pin 16)--------- Motor governor stage. • GND PRE GND (pin 1) ----------- Preamplifier stage, and power amplifier stage except for the power drive stage. PW GND (pin 11)----------- Power drive stage of power amplifier. GVN GND (pin 12)--------- Motor governor stage. • VREF It is necessary to stabilize the VREF circuit, because the internal circuit operate on this reference. • RF IN As this terminal is an input terminal of the ripple filter, it cannot supply a power supply to other ICs etc. • Preamplifier Input signal should be applied to VREF standard, otherwise pop noise become bigger when VCC is turned on and off. • Power amplifier It is necessary to insert the coupling capacitor through the PW IN terminal. In case that DC current or DC voltage is applied to the PW IN terminal, the internal circuit has unbalance and the power amplifier doesn’t operate normally. • Operating supply voltage range of motor governor stage As for the minimum of operating supply voltage range, the motor voltage is 1.8 V. In case that it is more than 1.8 V, the low voltage performance becomes bad. • PRE SW sensitivity (Ta = 25°C) Supply voltage VCC (V) PRE SW 1.5 V 1.8 V 0.5 V 0 1.5 2.0 2.5 3.5 4.0 3.0 2 4 1 3 1.2 V 3.0 V 3.6 V “H” PRE AMP: OFF |
