Texas Instruments TPA3223EVM Evaluation Module

Texas Instruments TPA3223EVM Evaluation Module demonstrates the TPA3223 pad-up integrated circuit. The TPA3223EVM is a complete reference design for the TPA3223, ready for evaluation and exceptional listening. The TPA3223 mono HD analog-input, Class-D amplifier provides an efficient operation at full power, idle, and standby. The TPA3223 has closed-loop feedback allowing low distortion across the audio band and delivering excellent sound quality. The TPA3223 operates in AD modulation and drives up to 2 x 200W into 4Ω load or 1 x 400W into 2Ω load.

The TI TPA3223EVM features adjustable gain settings from 20dB to 36dB, allowing flexible input signals with 1V_rms to 2V_rms single-ended/differential analog input interface. The device supports 2 x BTL (stereo) output channel or 1 x PBTL (mono) output channel configurations.

Features

Stereo HD Audio evaluation module
Device-integrated support for Single-Ended (SE) and Differential analog input signals

Integrated protection system (short circuit, clip, and thermal)
