TPA3123D2PWPR Texas Instruments Class-D Audio Amplifier HTSSOP-24 | JTDZ Tech
TPA3123D2PWPR — Overview
TPA3123D2PWPR by Texas Instruments is a component in the Class-D Audio Power Amplifier (Stereo / Analog Input) category, supplied by Shenzhen Jinteng Electronics Technology Co., Ltd. (JTDZ Tech) — an independent distributor serving OEMs, ODMs and EMS providers worldwide.
The TPA3123D2 is a 25-W-per-channel stereo Class-D audio power amplifier that drives single-ended stereo speakers (loads as low as 4 ohm) or a mono bridge-tied load. It operates from a single 10-V to 30-V supply and offers four selectable fixed gains (20/26/32/36 dB) with a built-in oscillator, thermal and short-circuit protection with auto recovery, and patented start-up/shutdown sequences that minimize pop noise. Its high Class-D efficiency eliminates the need for an external heat sink, and it is housed in a space-saving 24-pin HTSSOP (PWP) PowerPAD package aimed at televisions and consumer audio. TI lists the device as ACTIVE.
