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 NJM2135D NJM2135M equipment, cellular phones, for example.
