Product Overview

The TPA3125D2N is a 10W 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 TPA3125D2 can drive stereo speakers as low as 4Ω. The efficiency of the TPA3125D2 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. It operates in AD mode. There are two main configurations that may be used. For stereo operation, the TPA3125D2 should be configured in a single-ended (SE) half-bridge amplifier. For mono applications, TPA3125D2 may be used as a bridge-tied-load (BTL) amplifier. The traditional class-D modulation scheme, which is used in the TPA3125D2 BTL configuration, has a differential output where each output is 180 degrees out of phase and changes from ground to the supply voltage, VCC.
