1 Monaural BTL Output Clock-less Switching Driver for Class D Amplifier GENERAL DESCRIPTION PACKAGE OUTLE The NJU8789 is a monaural BTL output switching driver for class D amplifier including Separated Power Source terminals between Input and Output. It converts 1bit digital signal input, such as PWM or PDM signal. The NJU8789 realizes very high power-efficiency by class D operation. Therefore, It is suitable for portable set with speaker. NJU8789V FEATURES P CONFIGURATION Clock-less switching driver 1-channel 1bit Audio Signal Input Monaural BTL Output Standby(Hi-Z) Control Function Operating Voltage : 1.8V to 4.5V Driving Voltage : to 4.5V CMOS Technology Package Outline : SSOP10 NC TEST STBYb OUT P O OUT N BLOCK DIAGRAM O LEVEL SHIFTER OUT N STBYb LEVEL SHIFTER OUT P NJU8789 Ver

3 NJU3555 NJU8789 FUNCTIONAL DESCRIPTION (1) terminal (Input Signal) The input signals are PWM signals or PDM signals. (2) OUT P and OUT N terminal (Output Signal) The OUT P and OUT N generate PMW output signal The NJU8789 drives a speaker by the BTL output, and OUT P is a positive output and OUT N is a negative outputs. A switching regulator with a high response against a voltage fluctuation is the best selection for the O, which is the power supply for output drivers. (3) Standby Control Function By setting the STBYb terminal to L, the NJU8789 becomes standby condition. During standby condition, OUT P and OUT N are in Hi-Z. The STBYb terminal must be connected to when not using the Standby Function. Ver

Note 1) All voltage values are specified as =0V. Note 2) If the LSI is used on condition beyond the absolute maximum rating, the LSI may be destroyed. Using LSI within electrical characteristics is strongly recommended for normal operation. Use beyond the electrical characteristics conditions will cause malfunction and poor reliability. Note 3) De-coupling capacitors should be connected between - and O - due to the stabilized operation.
