ZTA4541 Datasheet | ZillTek

DESCRIPTION The unity gain stable ZTA4541 is both a mono differential output (for bridge-tied loads or BTL) audio power amplifier and a Single Ended (SE) stereo supply, the mono BTL mode delivers 85m W into an 8Ω load at 1% THD+N. In Single Ended stereo headphone mode, the amplifier delivers 14m W per channel into a 16Ω load at 1% THD+N. With the ZTA4541 packaged in the WLCSP-6, TDFN 3X3-10L and TDFN 2X2-8L packages. The package minimizes PCB area and maximizes output power. The ZTA4541 features circuitry that reduces output transients (“clicks” and “pops”) during device turnon and turn-off, an externally controlled, low-power consumption, active-low shutdown mode, and thermal shutdown. Zilltek audio power amplifiers are designed specifically to use few external ponents and provide high quality output power in a surface mount package.
