LM48512
Part of National’s PowerWise family or products, the LM48512 delivers 1.8W into 8Ω, while consuming 14.5mA of quiescent current.
The LM48512 also features National’s Enhanced Emissions Suppression (E
The LM48512 is designed to meet the demands of portable multimedia devices. The LM48512 features high efficiency compared
to other boosted amplifiers and low EMI Class D amplifiers. The LM48512 is capable of driving an 8Ω speaker to 5.5V levels
(1.8W) from a 3.6V supply while operating at 82% efficiency. Flexible power supply requirements allow operation from 2.3V
to 5.5V. The E
The LM48512 features a battery-saving automatic gain control (AGC). The AGC detects the battery voltage and reduces the gain of the amplifier to limit the output as the battery voltage decreases.
Superior click and pop suppression eliminates audible transients on power-up/down and during shutdown.
