ZTA4541 - 14mW Stereo Headphone Audio Amplifier

General 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 85mW into an 8Ω load at 1% THD+N.

Key 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 components and provide high quality output power in a surface mount package.

ZTA4541 0.9V, Mono 85mW BTL Output, 14mW Stereo Headphone Audio Amplifier 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 85mW into an 8Ω load at 1% THD+N. In Single Ended stereo headphone mode, the amplifier delivers 14mW 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.
