Product Summary
The TPA3123D2PWPR is a 25-W (per channel) efficient, Class-D audio power amplifier for driving stereo speakers in a single-ended configuration or a mono bridge-tied speaker. The TPA3123D2PWPR can drive stereo speakers as low as 4Ω. The efficiency of the TPA3123D2PWPR eliminates the need for an external heat sink when playing music. The gain of the amplifier is controlled by two gain select pins. The gain selections are 20, 26, 32, 36 dB. The patented start-up and shut-down sequences minimize pop noise in the speakers without additional circuitry. The applications of it is Televisions.
