TFA9879 Mono BTL class-D audio amplifier for portable applications with digital input Rev. 02 15 October 2010 Product data sheet 1. Introduction The TFA9879 is a high-efficiency filter-free mono class-D audio amplifier with two separate digital inputs for mobile applications. 2. General description The TFA9879 contains a processor that supports a range of sound processing features including a 5-band parametric equalizer, separate bass and treble control, a dynamic range compressor, soft clip control and volume control. Excellent audio performance combined with high Power Supply Rejection Ratio (PSRR) is achieved through the use of a closed loop configuration. 2 Two independent digital audio inputs (I S-bus / PCM / IOM2) are available for connecting both a baseband and a multimedia processor. The TFA9879 is available in a HVQFN24 package. 3. Features and benefits 3.1 General features Closed loop amplifier for: High power supply rejection ratio Excellent audio performance Digital input for high RF immunity High efficiency for maximizing battery life Wide supply voltage range (fully operational from 2.5 V to 5.5 V) Delivers high output power into 4 and 8 load impedances Phase-Locked Loop (PLL) no system clock required 2 Protection including diagnostics via I C-bus: OverCurrent Protection (OCP) to protect against short circuits across the speaker, to the supply line or to ground OverTemperature Protection (OTP) Digital inputs protected with UnderFrequency Protection (UFP), OverFrequency Protection (OFP) and Invalid Bit-clock Protection (IBP) Pop noise free at power-up/power down, during sample rate switching and when switching between digital inputs 2 Four separate I C-bus addresses for multi-channel applicationsTFA9879 NXP Semiconductors Mono BTL class-D audio amplifier with digital input 1.8 V / 3.3 V tolerant digital inputs Only three external components required 3.2 Programmable Digital Sound Processor (DSP) Digital volume control (70 dB to +24 dB) Digital parametric 5-band equalizer Bass and treble control (18 dB to +18 dB) Dynamic range compressor: Programmable attack and release levels Programmable attack and release rates Soft and hard mute control Programmable DC blocking via high-pass filter Power limiter (0 dB to 124 dB in 0.5 dB steps) Zero crossing volume control Stereo-to-mono down-mix function 3.3 Interface format support for digital audio inputs 2 I S formats (f = 8 kHz to 96 kHz): s 2 Philips standard I S-bus 2 Japanese I S-bus MSB-justified 2 Sony I S-bus LSB-justified PCM / IOM2 formats (f = 8 kHz or f = 16 kHz): s s Long frame sync Short frame sync 4. Applications Mobile phones Portable Navigation Devices (PND) PDAs Notebooks Portable gaming devices MP3 and MP4 players TFA9879 All information provided in this document is subject to legal disclaimers.
