Power Amplifier with 3D Enhancement
Check for Samples: LM48410 FEATURES DESCRIPTION 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. 1 2 Selectable Spread Spectrum Mode Reduces
