Frequently Asked Questions

What is the nominal output power and harmonic distortion level of the LM4951ASD?

The LM4951ASD delivers 1.8 W of nominal output power with a harmonic distortion specification of 1% THD, providing acceptably clean audio reproduction for mono speaker applications such as alarm clocks, portable radios, and consumer electronic devices where size and cost constraints are primary design drivers.

For a compact alarm clock PCB, how does the 10-pin SOIC no-lead package of LM4951ASD compare to a DIP alternative?

The 10-pin SOIC no-lead package of LM4951ASD occupies a footprint of approximately 3x3 mm, far smaller than a DIP-8 package which exceeds 10 mm in length. This compact footprint enables tighter PCB layouts in space-constrained consumer products like alarm clocks and small Bluetooth speakers delivering 1.8 W output power.

In which portable consumer applications is the LM4951ASD 1.8 W mono amplifier most commonly used?

The LM4951ASD suits portable radios, handheld game consoles, tablet secondary speakers, and battery-operated alarm devices requiring a single 1.8 W mono audio channel with minimal external component count. Its 1% THD ensures adequate audio fidelity for voice, alert tones, and music reproduction in devices with supply voltages typical of 3.3 V to 5 V systems.

How does the LM4951ASD compare to the LM4950 for single-speaker consumer product designs?

The LM4951ASD and LM4950 are both mono audio amplifiers in the LM495x family targeting 1 W to 2 W speaker drivers, with LM4951ASD specified at 1.8 W nominal output. For designs already using LM4950 at lower power, migrating to LM4951ASD in the same 10-pin SOIC no-lead footprint provides additional output headroom without PCB layout changes or increased board area.
