CS4412A

DC ELECTRICAL CHARACTERISTICS

GND = PGND = 0 V; All voltages with respect to ground; PWM switch rate = 384 kHz; Unless otherwise specified.

Notes:

3. Normal operation is defined as RST12 and RST34 = HI.

4. Power-Down Mode is defined as RST12 and RST34 = LOW with all input lines held static.

5. Power supply current increases with increasing PWM switching rates.
