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 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 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
ON
resistance,
0.5 max @ 2.8 V V
CC
.
The NLMD5820 processes analog inputs with a pulse width
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 V noise floor, A-weighted, clean listening is guaranteed no matter
the load sensitivity.
