PA3428 Datasheet



As a stereo audio speaker which is operating on a single 5V
supply, the UTC PA3428 is capable of delivering 2W of output
power per channel into 4Ω loads with less than 1% THD+N.  
Way of two terminals (GAIN0 and GAIN1) can configured and
control the amplifier gain. It also provide gain settings of 2, 6, 12,
and 24V/V.  
Other features include internal gain control which requires few
external components, an active-low shutdown mode input and
thermal shutdown protection.

* Internal Depop circuitry  
* Output power at 1% THD+N
Supply voltage:5V
Delivering 2.0W into a 4Ω load
Delivering 1.2W into a 8Ω load
* Tow mode:
Bridge-tied Load (BTL),  
Single-ended (SE)
* Stereo input signal
* Fully differential input
* Gain control Internally
* Differential Input fully
