Overview
The NCP2823A/B are cost effective mono audio power
amplifiers designed for portable electronic devices.
NCP2823A is optimized for 8 W operation and NCP2823B
can operate with speaker impedance down to 4.0 W. For
Instance, NCP2823B is capable of delivering 3 W of
continuous average power to a 4.0 W from a 5.0 V supply in
a Bridge Tied Load (BTL) configuration. Under the same
conditions, NCP2823A can provide 1.5 W to an 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 transducers. With
more than 95% efficiency and very low shutdown current,
it increases the lifetime of your battery and drastically
lowers the junction temperature.
The intent of the evaluation boards is to illustrate typical
operation of the NCP2823 device for laboratory
characterization. The NCP2823 Series Evaluation Board
schematic is depicted in Figure 3.
