TFA9879HN/N1,157

Overview

The TFA9879HN/N1,157 is a high-efficiency mono Class-D audio amplifier with digital inputs. It operates on a supply voltage range of 2.5 V to 5.5 V and delivers up to 2.75 W output power into an 8-ohm load at 5.0 V. The device features a closed-loop configuration for excellent audio performance and high power supply rejection ratio (PSRR). It includes a programmable DSP with a 5-band equalizer, bass/treble control, and dynamic range compression.

Feature Summary

Integrated programmable digital sound processor featuring a 5-band parametric equalizer, bass and treble controls, and dynamic range compressor.
Dual independent digital audio inputs supporting I2S and PCM/IOM2 formats for connection to baseband and multimedia processors.
Comprehensive protection circuits including overcurrent, overtemperature, underfrequency, overfrequency, and invalid bit-clock protection.
Pop-noise-free operation during power-up, power-down, sample rate switching, and digital input selection.

Applications

Mobile phones
Portable Navigation Devices (PND)
Notebooks
Portable gaming devices
