NLMD5820 2.65 W Filterless Class-D Audio Amplifier with Integrated Dual SPST Switch The NLMD5820 is an integrated mono Class-D audio power amplifier and dual SPST switch capable of delivering 2.65 W of continuous average power to 4.0 W from a 5.0 V supply in a Bridge Tied Load (BTL) configuration. Under the same conditions, the output power stage can provide 1.4 W to a 8.0 W BTL load with less than 1% THD+N. For cellular handsets or PDAs it offers space and cost savings because no output filte.
