TPA3123D2PWP Description
The TPA3123D2PWP is a 25W Stereo Class-D Audio Amplifier with SE outputs for driving stereo speakers in single-ended mode or a bridge-tied-load mono speaker. The TPA3123D2 is capable of driving stereo speakers as low as 4R. When playing music, the TPA3123D2's efficiency eliminates the need for an external heat sink. The amplifier's gain is controlled by two gain select pins. The gain options are 20, 26, 32, and 36dB. Without the use of additional circuitry, the patented start-up and shut-down sequences reduce pop noise in the speakers. It works in AD mode. There are two main configurations available. The TPA3123D2 should be used in a single-ended (SE) half-bridge amplifier for stereo operation.
