s Usage Notes
1. Care should be taken so as not to cause any of the following conditions on use of this IC. If the following conditions
come up, the IC is likely to break down or to be smoking.
Short-circuit between output pins
Short-circuit between output pin and GND
Short-circuit between output pin and power supply
(Output pin refers to any of those Fo1 (pin 8), Ro1 (pin 6), Fo2 (pin 9), Ro2 (pin 11), Fo3 (pin 24), Ro3 (pin 22),
Fo4 (pin 25), Ro4 (pin 27). GND refers to any of those GND (pin 14), PGND1 (pin 7), PGND2 (pin 10), PGND3
(pin 23), PGND4 (pin 26). Power supply refers to any of those VC (pin 2), VGI (pin 19), VM1 (pin 1), VM2 (pin16),
VM3 (pin 17), VM4 (pin 32).
2. VM1 monitor pin (pin 3) outputs approximately one half of VM1 voltage and its upper limit is VC supply voltage. This
is meant to prevent the DSP connected to this Pin from damage when the voltage exceeding an operating supply
voltage range is inputted to the VM1 pin. On use of this pin, therefore, note that no value exceeding VC is outputted.
