The LPA4732 stereo headphone amplifiers are designed for portable equipment where board space is at a premium. The LPA4732 deliver up to 215mW per channel into a 16Ω load or 194mW into a 32Ω load and have low 0.003% THD+N. An 78dB at 217Hz power-supply rejection ratio (PSRR) allows these devices to operate from noisy digital supplies without an additional linear regulator. Comprehensive anticlick-and-pop circuitry suppresses audible clicks and pops on startup and shutdown. A low-power shutdown mode reduces the supply current to 0.1µA. The LPA4732 operates from a single 2.5V to 5.5V supply, consumes only 5mA supply current, and is specified over the extended -40 ℃ to +85 ℃ temperature range. The devices are available in tiny 16-pin TQFN (3mm✕ 3mm✕0.8mm) packages.
