General Description
The LPA4722A stereo headphone amplifiers aredesigned for portable equipment where board space isat a premium. The LPA4722A deliver up to 215mW perchannel into a 16Ω load or 200mW into a 32Ω load andhave low 0.005% THD+N. An 80dB at 217Hzpower-supply rejection ratio (PSRR) allows thesedevices to operate from noisy digital supplies without anadditional linear regulator. Comprehensiveanticlick-and-pop circuitry suppresses audible clicksand pops on startup and shutdown. A low-powershutdown mode reduces the supply current to 0.1μA.The LPA4722A operates from a single 2.5V to 5.5Vsupply, consumes only 5mA supply current, and isspecified over the extended -40 ℃ to +85 ℃temperature range. The devices are available in tiny16-pin TQFN (3mmx3mmx0.8mm) packages.
