NJU7084 www..com HIGH-POWER & LOW-VOLTAGE AUDIO POWER AMPLIFIER s GENERAL DESCRIPTION The NJU7084 is an audio power amplifier designed for telephone applications. No external coupling capacitors are required because of the differential outputs. The closed loop gain is adjusted by two external resistors, and a SD pin permit power down with muting the input signal. The NJU7084 improves high output power compared with other amplifier. sAPPLICATION qCell Phone, PHS qPortable Telephone, Wireless Telephone qWhite Goods qSecurity Alarm qMonitor s PACKAGE OUTLINE NJU7084R NJU7084M s FEATURES qOperating Voltage qOperating Current qSupply Current in Shutdown Mode qOutput Power qThermal Shutdown Circuit q C-MOS Technology q Package Outline V+=2.8 to 5.5V IDD1=2.5mA typ.
