It is a mono (1-channel) device in a through-hole TO-220-5 package with formed leads, rated for the commercial temperature range of 0°C to 70°C. Typical applications include active speakers, powered subwoofers, home-theater amplifiers, and general-purpose audio line drivers where a single-chip solution with modest heatsinking is preferred over discrete designs. ## Supply range and output — what they mean for the BOM The supply range of 16V to 60V (or ±8V to ±30V) covers most common audio rails. The 25W output at 8Ω is the headline figure.","metaTitle":"LM1875T/LB05 Class AB Audio Amp IC, 25W Mono TO-220-5","metaDescription":"LM1875T/LB05 Class AB audio amplifier IC delivers 25W into 8Ω mono.
