RT9114C

Dual Channel Digital Audio System with EQ and Frequency

DRC Control

General Description

Features

The RT9114C is a high efficiency, I²S-input, stereo

channel audio power amplifier delivering 2x20W into 8

BTL speaker loads. It can deliver over 90% power

efficiency and eliminate the need for heat-sink.

 Wide Input Supply Range : 8V to 26.4V

 2x20W at into 8 BTL at 20V

 2x9W at into 8 BTL at 12V

 Support Stereo/PBTL/Mono Output

 Sampling Frequency from 8kHz to 96kHz with

Auto Detection

 Support Master and Slave I²S Interface

 MCLK-Less with Clock Auto Detection

 Built-In Anti-Pop Function

The built-in anti-pop functions can reduce the speaker’s

pop noise under all kind of scenarios. Built-in protection

circuits can provide over-temperature, over-current,

over-voltage, and under-voltage protections and report

error status.

 Support SDO for Acoustic Echo Cancellation

 > 24 Programmable Biquads

 Programmable Coefficients for DRC Filters and

Supporting Multi-Compression Ratios with post

DRC

The RT9114C is an I²S device receiving all clocks from

external sources with wide input sampling rate from

8kHz to 96kHz. A fully programmable data path routes

these channels to the internal speaker drivers. Besides,

the RT9114C also supports the master mode if an

external MCLK is ready.

 Built-In DC Blocking Filters

 Protection Features : UVLO, OVP, OCP, OTP and

DCP

The RT9114C features three band DRC and flexible

multi-band biquads for anti-clipping, power limiting, and

speaker equalization.

 Filter-Less Application

 VQFN-28L Thermally-Enhanced Package

 RoHS Compliant and Halogen Free

Applications

 LCD-TV

 Monitors

 Home Audio

 Amusement Equipment
