RT9101ZQW - 2.65W PWM Class-D Power Amplifier

This page provides the datasheet information for the RT9101ZQW, a member of the RT9101 2.65W PWM Class-D Power Amplifier family.

Description

The RT9101 is a 2.65W, high efficiency Class-D audio amplifier featuring low-resistance internal power MOSFETs and the gain can be set by an external input resistance.

The filter free topology eliminates the output filter and reduces the external component count, footprint area, and system costs.

Features

  • the RT9101 provides a fast startup time to minimize audible popping during device turn-on and turnoff. Moreover, the RT9101 also integrates thermal and over current protection circuits. The RT9101 is available in WDFN-8L 3x3, and WL-CSP-9B 1.45x1.45 (BSC) packages. Ordering Information RT9101 ( ) Package Type QW : WDFN-8L 3x3 (W-Type) WSC : WL-CSP-9B 1.45x1.45 (BSC) Lead Plating System G : Green (Halogen Free and Pb Free) Z : ECO (Ecological Element with Halogen Free and Pb free) Default : WDFN.

RT9101 2.65W PWM Class-D Power Amplifier General Description The RT9101 is a 2.65W, high efficiency Class-D audio amplifier featuring low-resistance internal power MOSFETs and the gain can be set by an external input resistance. The filter free topology eliminates the output filter and reduces the external component count, footprint area, and system costs. Operating from a single 5V supply, the RT9101 is capable of driving 4Ω speaker load at a continuous average output of 2.65W/10% THD+N or 2W/0.5% THD+N. The RT9101 has a higher efficiency with speaker load compared to a typical class AB amplifier. With a 3.6V supply driving an 8Ω speaker, the efficiency for a 400mW power level is 88%.
