TPA3138D2PWPR 原装 音频放大器

放大器 IC 1-通道(单声道)或 2-通道(立体声) D 28-HTSSOP

 

TPA3138D2PWPR 原装 音频放大器 的描述:

The TPA3138D2 is a 10-W/ch, high-efficiency, low-idle-current Class-D stereo audio amplifier. It can drive stereo speakers with a load as low as 3.2-Ω. In the 1SPW mode, it consumes a low idle current of only 21-mA (12-V) and can operate down to 3.5-V, allowing for longer audio play and improved thermal performance in bluetooth speakers, battery-powered appliances and other power-sensitive applications.

Advanced EMI Suppression with Spread Spectrum Control enables the use of inexpensive ferrite bead filters while meeting EMC requirements for system cost reduction.

To further simplify the design, the TPA3138D2 integrates essential protection features including undervoltage, overvoltage, power limit, short circuit, overtemperature, as well as DC speaker protection. All of these protections come with automatic recovery.

Customers can leverage every TPA3138D2 feature in existing designs as it is fully pin-to-pin compatible to TIs TPA3110D2, TPA3136D2 and TPA3136AD2.
