| j s GENERAL DESCRIPTION The NJM2151A is a monaural audio power amplifier and stereo headphone amplifier for wide voltage operation. The NJM2151A was stereo headphone power amplifier for low distortion single-end output , and monaural power amplifier for high power bridge(BTL). The NJM2151A operate low voltage supply , low operating current and low power-down current. The NJM2151A includes MUTE , SUSPEND mode, and suitable for NOTE PC, PDA, CAMCODER, and other battery equipment. The NJM2151AVF1 is packaged in the power package. NJM2151A MONAURAL POWER AMP. & HEADPHONE POWER AMP.
