G= 60kΩ RIN1+100 (Ω) ×2 The power supply for Ch.1 and 2 is supplied from Pin20 and the power supply for Ch.3 and 4 is supplied from Pin9 independently. Output amplitude is increased by increasing the supply voltage. Set the power supply voltage as necessary. However, always set Pin7 of VCC to the maximum electric potential. Pin8 and 21 may require a capacitor for ripple removal. As protection functions, VCC reset circuit,VREF detector and heat protection circuit are incorporated. The VCC reset circuit operates at approx. 3V and is released at 3.2V, when the supply (Pin7) decreases. For the VREF detector, the protection function works at approx. 1V (max. 2V). Also, the set temperature for operation of the heat protection circuit is approx. 180˚C . PC (Power Cut) functions which can be independently controlled are incorporated in Ch.1 and 2. • 5V Supply By adding an external PNP transistor, 5V regulator can be constructed. Attach an external capacitor for loop filter to output Pin2. In Pin1, the base current limiting circuit (typ. 10mA) is incorporated. When the V supply is used, the external PNP Tr emitter must be connected to pin than Pin7 (SVCC pin) • OP Amp.

(1) Load current, IP1 flowing in loads RL1 and RL2 is supplied through Pin20. IP1 = | V18 –V17 | | V16 –V15 | + RL1 RL2 (2) Load current, IP2 flowing in loads RL3 and RL4 is supplied through Pin9. IP2 = | V14 –V13 | | V12 –V11 | + RL3 RL4 (3) Dissipation increase (DPd) inside the IC (power output stage) caused by loads RL1, RL2, RL3, RL4 is as follow. | V18 –V17 | | V16 –V15 | + (PVCC1 – | V16 –V15 | ) × RL1 RL2 | V14 –V13 | | V12 –V11 | + (PVCC2 – | V14 –V13 | ) × + (PVCC2 – | V12 –V11 | ) × RL3 RL4 DPd = (PVCC1 – | V18 –V17 | ) × (4) Dissipation increase (DPS) inside the IC (signal block supplied from Pinu) caused by loads RL1, RL2, RL3, RL4 is almost as follows ; V1 V2 (2SVCC + | V18 –V17 | ) + (2SVCC + | V16 –V15 | ) R1 R2 V3 V4 (2SVCC + | V14 –V13 | ) + (2SVCC + | V12 –V11 | ) + R3 R4 DPS = 3 (5) Dissipation increase during driver running is DPd + DPS. (6) Inside loss under no load (Pd1) is almost as follows ; Pd1 = SVCC × I (SVCC) + PVCC1 × I (PVCC1) + PVCC2 × I (PVCC2) (7) Entire IC inside loss (Pd) is almost as follows ; Pd = Pd1 + DPd + DPS
