TPA3123D2PWP

The TPA3123D2PWP is a 25W Stereo Class-D Audio Amplifier with SE outputs for driving stereo speakers in a single-ended configuration or a mono speaker in a bridge-tied-load configuration. The TPA3123D2 can drive stereo speakers as low as 4Ω. The efficiency of the TPA3123D2 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, 36dB. The patented start-up and shut-down sequences minimize pop noise in the speakers without additional circuitry. It operates in AD mode. There are two main configurations that may be used. For stereo operation, the TPA3123D2 should be configured in a single-ended (SE) half-bridge amplifier. For mono applications, TPA3123D2 may be used as a bridge-tied-load (BTL) amplifier.
