FUNCTIONAL DESCRIPTION

(1) Output Signal

converted to analog signal via external 2nd-order or higher LC filter. A switching regulator with a high response

drivers. To obtain better T.H.D. performance, the stabilization of the power is key.

(2) Standby

By setting the STBY pin to “L”, the standby mode is enabled. In the standby mode, the entire functions of the

(3) Mute

wave(Duty: 50%).

(4) Low Voltage Detector

(5) Short Protection Circuit

The short protector, which protects the NJU8752 from high short-circuit current, turns off the output driver.

After about 5 seconds from the protection, the NJU8752 returns to normal operation. The short protector is

enabled in response to the following accidents.

Note 1) The detectable current and the period for the protection depend on the power supply voltage

and ambient temperature.

Note 2) The short protector is not effective for a long term short-circuit but for an instantaneous accident.

Continuous high-current may cause permanent damage to the NJU8752.
