DESCRIPTION

· The TFA8200 is a high-efficiency, filter-free mono class-D audio amplifier designed for IoT applications. It features two separate digital inputs and includes a processor supporting various sound processing features such as a 5-band parametric equalizer, bass and treble control, dynamic range compressor, soft clip control, and volume control. The amplifier operates in a closed loop configuration to ensure high power supply rejection ratio and excellent audio performance. It is housed in an HVQFN24 package.

FEATURES

· Closed loop amplifier for high power supply rejection ratio and excellent audio performance.
· Digital input for high RF immunity.
· High efficiency to maximize battery life.
· Wide supply voltage range (2.5 V to 5.5 V).
· High output power for 4 Ω and 8 Ω load impedances.
· Phase-locked loop (PLL) eliminates the need for a system clock.
· Comprehensive protection features including overcurrent, overtemperature, and digital input protections.
· Pop noise-free operation during power-up/power down, sample rate switching, and digital input switching.
· Four separate I2C-bus addresses for multi-channel applications.
· 1.8 V/3.3 V tolerant digital inputs.
· Requires only three external components.

APPLICATIONS

· IoT devices requiring high-efficiency audio amplification.
· Systems needing robust audio performance with minimal external components.
· Applications requiring flexible digital audio inputs and comprehensive sound processing features.
