PA4894
1.8 WATT DIFFERENTIAL AUDIO POWER AMPLIFIER WITH SELECTABLE SHUTDOWN
CMOS IC
DESCRIPTION
The UTC PA4894 is a differential audio power amplifier, characterized by its selectable shutdown mode for flexible operation. Shutdown may be enabled by either logic high or low depending on the voltage applied on the SD MODE pin and the shutdown mode features low power consumption.
This device provides customers perfect sound performance by its high quality audio, moreover, less external components and lower power dissipation are required.
Operating with a 5.5V power supply, the UTC PA4894 is capable of driving an 8.0Ω load at a continuous average output of 1.8W under a 10% THD+N. If it works with a 5.0V voltage under the same load conditions, 1.
