It's built for audio output stages in powered speakers, stereo receivers, instrument amplifiers, and general-purpose line drivers where a single-channel, through-hole TO-220-5 package is preferred. The wide supply range — 16V to 60V single or ±8V to ±30V dual — means it can sit on a variety of existing rail architectures without a custom supply design. ## 25W into 8Ω — what that means for your BOM The 25W rating into 8Ω is the continuous output per channel; this part is a single-channel (mono) device, so a stereo design needs two. The TO-220-5 package with formed leads suits through-hole assembly and moderate heatsinking — plan for a heatsink rated to handle the thermal dissipation at your target output level. The short-circuit and thermal protection built in means you can skip external clamp or crowbar circuits in most consumer and pro-audio builds, saving board space and BOM cost. ## Sourcing and lifecycle — still in active production The LM1875T/LF05 is listed as Active on the manufacturer's lifecycle record, with ROHS3 compliance. No last-time-buy or end-of-life notice is in effect. This part is sourced through independent distribution; availability and current pricing are confirmed at quote time. ## Mounting and thermal considerations Through-hole TO-220-5 package with formed leads. The tab is the output-stage ground — electrically connected to the negative rail in split-supply configurations, so the heatsink must be isolated or the mounting hardware must insulate the tab. Operating temperature range is 0°C to 70°C ambient, which covers indoor audio equipment but not automotive or outdoor enclosures without derating.","metaTitle":"LM1875T/LF05 Class AB Audio Amplifier IC, 25W Mono, TO-220-5","metaDescription":"LM1875T/LF05 Class AB mono amplifier delivers 25W into 8Ω.

The base LM1875T is the non-ROHS version. Electrically and functionally they are identical — same 25W output, same TO-220-5 package, same supply range."},{"question":"What are the typical applications of LM1875T/LF05?","answer":"This Class AB amplifier is used in audio output stages for powered speakers, stereo receivers, instrument amplifiers, and general-purpose line drivers needing 25W into 8Ω from a single or split supply."},{"question":"Can I use LM1875T/LF05 in a bridged configuration?","answer":"The LM1875T/LF05 is a single-channel (mono) device. Bridging requires two identical amplifiers with an inverted input signal. The datasheet provides application circuits for bridged operation; the output power into 8Ω roughly doubles, but the load impedance seen by each amplifier halves, so thermal and current limits must be respected."},{"question":"What is the pinout of LM1875T/LF05?","answer":"The TO-220-5 pinout (viewed from the front with leads down) is: pin 1 — non-inverting input, pin 2 — inverting input, pin 3 — V- / ground, pin 4 — output, pin 5 — V+. The metal tab is electrically connected to pin 3 (V- in split-supply use)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM1875T-LF05","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM1875T-LF05 when reusing this data.
