PT5322 - Dual 2.2W Audio Amplifier plus Stereo Headphone Function
Powtech
General Description
The PT5322 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W to a 4Ω load or 2.4W to a 3Ω load with less than 1.0% THD+N.
In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones.
Key Features
a low-power consumption shutdown mode and thermal shutdown protection. It also utilizes circuitry to reduce “pop and click” during device turn-on. The PT5322 is available in a 16 or 20 pin TSSOP package.

In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones. The PT5322 has a HP (headphone) enable input, which activates the single ended headphone mode and disables the BTL output mode. The HP_Sense input is for use with a normal stereo headphone jack. The PT5322 features a low-power consumption shutdown mode and thermal shutdown protection. It also utilizes circuitry to reduce “pop and click” during
