The Class G architecture switches between multiple supply rails to reduce power dissipation at lower output levels — a meaningful efficiency gain over Class AB when the headphone output is idle or playing at moderate volume. Typical application is portable audio: smartphones, tablets, handheld gaming consoles, and Bluetooth speakers where battery life and PCB area are tight. ## Package and assembly constraints The 25-DSBGA is a wafer-level chip-scale package with no molded body — the die is the package. ## Protection features and shutdown behavior The TPA6166A2YFFT integrates Depop (pop/click suppression on power-up and shutdown), Short-Circuit Protection, and Thermal Protection plus a Shutdown input. The depop circuit is worth a close read in the datasheet: it sequences the internal bias ramp to prevent the DC transient that otherwise hits the headphones at power-on. Short-circuit protection is current-limiting, not latching — the amplifier recovers when the fault clears. Thermal protection thresholds are set above the maximum operating temperature, so sustained high-power drive into a low-impedance load will trigger shutdown before die damage.","metaTitle":"TPA6166A2YFFT Class G Stereo Headphone Amp, 30mW, 25-DSBGA","metaDescription":"TI TPA6166A2YFFT Class G stereo headphone amplifier delivers 30mW per channel into 16Ω.
