RT9101

2.65W PWM Class-D Power Amplifier

General Description

Features

^zWide Operating Voltage : 2.5V to 5.5V

^zHigh Efficiency With an 8Ω Speaker :

` 88% at 400mW

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.

` 80% at 100mW

^zLow Quiescent Current and Shutdown Current

^zOptimized PWM Output Stage Eliminates LC Filter

^zFully Differential Design Reduces RF Rectification

and Eliminates Bypass Capacitor

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%.

^zInternally Generated 250kHz Switching Frequency

^zIntegrated Pop and Click Suppression Circuitry

^zRoHS Compliant and Halogen Free

Applications

z Mobile Phones

It is very suitable for power sensitive application, such as

cellular handsets and battery powered devices. In addition

to these features, the RT9101 provides a fast startup time

to minimize audible popping during device turn-on and turn-

off. Moreover, the RT9101 also integrates thermal and over

current protection circuits.

z Handsets

z PDAs

z Portable multimedia devices
