NLMD5820

2.65 W Filterless Class-D

Audio Amplifier with

Integrated Dual SPST Switch

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 filter is required when using inductive

tranducers. The NLMD5820 incorporates a dual SPST switch which

allows signals to bypass the amplifier. The integrated switch operates

off a separate supply voltage and maintains a very low R

0.5 W max @ 2.8 V V

modulation technique that lowers output noise and THD when

compared to a conventional sigma-delta modulator. The device allows

independent gain while summing signals from various audio sources.

Thus, in cellular handsets, the earpiece, the loudspeaker and even the

melody ringer can be driven with a single NLMD5820. Due to its low

42 mV noise floor, A-weighted, clean listening is guaranteed no matter

the load sensitivity.
