It integrates depop circuitry to eliminate power-on clicks and accepts differential inputs for common-mode noise rejection — useful in portable audio where the ground plane is shared with a switching regulator or digital core. The 16-WQFN (3x3 mm) package fits tight layouts on media players, smartphone audio daughterboards, or portable gaming hardware. ## Depop and differential inputs — click-free startup and noise rejection Depop ramps the output bias voltage slowly at power-on, preventing the audible pop that occurs when a DC-coupled amplifier connects to headphones. The differential inputs reject ground noise picked up between the audio codec and the amplifier — a common issue in two-layer PCBs where the analog return path shares a via with a digital return. Shutdown mode (pin-controlled) drops quiescent current to near zero, extending battery life in devices that pause audio between tracks.","metaTitle":"TPA6132A2RTER Class AB Stereo Headphone Amp, 25mW, 16-WQFN","metaDescription":"TI TPA6132A2RTER Class AB stereo headphone amplifier, 25mW x 2 into 16Ω, 2.3-5.5V supply, depop, differential inputs, 16-WQFN.
