TPA3123D2PWPR Description

Short technical summary and product information.

The TPA3123D2PWPR is an efficient Class-D audio power amplifier from Texas Instruments, designed for driving stereo speakers in a single-ended configuration or a mono speaker in a bridge-tied-load configuration. It can deliver up to 25W per channel into a 4Ω load from a 27V supply, or 20W per channel into a 4Ω load from a 24V supply.

 

This amplifier operates from a wide supply voltage range of 10V to 30V. Its Class-D operation is highly efficient, often eliminating the need for an external heat sink. Key electrical specifications include a typical THD + N of 0.08% at 1 kHz and a minimum load impedance of 4Ω.

 

The TPA3123D2PWPR features analog inputs and a hardware control interface. It offers four selectable fixed-gain settings (20, 26, 32, 36 dB) controlled by gain select pins. The device includes internal oscillation, advanced power-off pop reduction, and thermal and short-circuit protection with auto-recovery.

 

Packaged in a space-saving 24-pin TSSOP (HTSSOP PWP) surface-mount package, this amplifier is suitable for various audio applications, including televisions. The package dimensions are 7.8 mm x 6.4 mm with an area of 49.92 mm².
