NJM2135D

NJM2135 LOW VOLTAGE AUDIO POWER AMPLIFIER ■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE The NJM2135 is a Low voltage audio power amplifier for speaker drivers.No external coupling capacitors are required because of the differential output.The closed loop gain is adjusted by two external resistors.The low supply current in power down mode contributes to the reduction of power consumption of portable battery powered equipment,cellular phones,for example. NJM2135D ■ FEATURES ● Operating Voltage ( +2V~+16V ) ● Low Operating Current in Power Down Mode ( 0.1µA typ. ) ● Low Operating Current in Normal Operation Mode ( 2.7mA typ. ) ● Output Power Exceeds 250mW ( V+=6V,RL=32Ω ) ● Gain Range ( GVD=0~43dB,Voice Band ) ● Load Impedance ( 8~200Ω ) ● Bipolar Technology ● Package Outline DIP8,DMP8,SIP8,SSOP8,VSP8 ■ PIN CONFIGURATION NJM2135M NJM2135L NJM2135E NJM2135V NJM2135R PIN FUNCTION 1.
