Min Voltage (typical range): 2.4 V
Description
The LM48310 is a single supply, high efficiency, mono, 2.6W, filterless switching audio amplifier. The LM48310 features National’s Enhanced Emissions Suppression (E2S) system, that features a unique patent-pending ultra low EMI, spread spectrum, PWM architecture, that significantly reduces RF emissions while preserving audio quality and efficiency.
Key Features
- The E2S system improves battery life, reduces external component count, board area consumption, system cost, and simplifying design
- The LM48310 is designed to meet the demands of portable multimedia devices
- Operating from a single 5V supply, the device is capable of delivering 2.6W 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 LM48310 offers two logic selectable modulation schemes, fixed frequency mode, and an EMI suppressing spread spectrum mode
