The 1W into 8Ω rating defines the mono speaker channel capability. The 85mW into 32Ω headphone output covers typical earbud or headphone loads.
The 0.118-inch body width (3.00 mm) is standard for this footprint family. The part is also listed as 10-PowerTFSOP — same mechanical outline, same land pattern. The shutdown pin is active-low; leave it tied to VDD if not used. The depop feature is internal; no external timing capacitor is required.
The TPA0253DGQR delivers 1W into an 8Ω load on the mono speaker channel, and 85mW per channel into 32Ω headphones.
The TPA0253DGQR is a Class AB amplifier, which offers lower distortion than Class D at the cost of lower efficiency — typical for battery-powered audio where audio quality matters over power savings.
