Output power and load — what the ratings mean for your design
The 1W into 8Ω rating defines the mono speaker channel capability. The 85mW into 32Ω headphone output covers typical earbud or headphone loads.
Package and pinout
The TPA0253DGQR is supplied in a 10-lead MSOP with an exposed thermal pad (HVSSOP). 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.
