Description

General part information

LM48410 Series

The LM48410 is a single supply, high efficiency, 2.3W/channel, filterless switching audio amplifier. A low noise PWM architecture eliminates the output filter, reducing external component count, board area consumption, system cost, and simplifying design. A selectable spread spectrum modulation scheme suppresses RF emissions, further reducing the need for output filters.

The LM48410 is designed to meet the demands of mobile phones and other portable communication devices. Operating from a single 5V supply, the device is capable of delivering 2.3W/channel of continuous output power to a 4Ω load with less than 10% THD+N. Flexible power supply requirements allow operation from 2.4V to 5.5V. The LM48410 offers two logic selectable modulation schemes, fixed frequency mode, and an EMI reducing spread spectrum mode.

The LM48410 features high efficiency compared with conventional Class AB amplifiers. When driving an 8Ω speaker from a 3.6V supply, the device operates with 85% efficiency at PO= 500mW/Ch. Four gain options are pin selectable through the G0 and G1 pins. The LM48410 also includes 3D audio enhancement that improves stereo sound quality. In devices where the left and right speakers are in close proximity, 3D enhancement affects channel specialization, widening the perceived soundstage.
