TFA9879

The TFA9879 is designed as one kind of high-efficiency filter-free mono class-D audio amplifier device that 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.

Features of the TFA9879 are:(1)Digital input for high RF immunity; (2)High efficiency for maximizing battery life; (3)Wide supply voltage range (fully operational from 2.5 V to 5.5 V); (4)Delivers high output power into 4 and 8 load impedances; (5)Phase-Locked Loop (PLL); no system clock required; (6)"op noise" free at power-up/power down, during sample rate switching and when switching between digital inputs; (7)Four separate I2C-bus addresses for multi-channel applications. And it can be used in (1)Mobile phones; (2)Portable Navigation Devices (PND); (3)PDAs; (4)Notebooks; (5)Portable gaming devices; (6)MP3 and MP4 players applications.

The absolute maximum ratings of the TFA9879 can be summarized as:(1)analog supply voltage: -0.3 to +5.5 V;(2)digital supply voltage: -0.3 to +1.95 V;(3)junction temperature: +150 °C;(4)storage temperature: -55 to +150 °C;(5)ambient temperature: -20 to +85 °C;(6)electrostatic discharge voltage (HBM): -2 to +2 kV.
