PT5322 Datasheet (Powtech) - Dual 2.2W Audio Amplifier plus Stereo Headphone Function

PT5322, Dual 2.2W Audio Amplifier plus Stereo Headphone Function

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.

PT5322 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. FEATURES z z z z z z z z z z PO@1% THD+N: 3Ω, 4Ω loads: 2.2W (typ), 2.0W (typ) 8Ω load: 1.3W (t
