PT2832
22W x 2, Class-D Audio Power Amplifier
DESCRIPTION
FEATURES
The PT2832 is a Class-D power amplifier designs for
audio system; the maximum output power could up
to 22W x 2. It is housing in a small, thermal enhanced
package, the best benefits of the PT2832 are high
efficiency and less external components. Fabricated
by high voltage BCD process to improve ESD and
electro stress handling capabilities.
Supports Multiple Output Configurations
(THD=10%)
