That output level suits a single speaker in a portable speaker, a tablet, or a small soundbar where board area is tight and efficiency matters. ## Package and mounting Depop circuitry suppresses the pop on power-up and shutdown, which saves a design cycle adding an external mute transistor. Differential inputs reject ground noise on long input traces — useful when the audio source is a codec on a separate board. Short-circuit and thermal protection let the amp survive a speaker-wire short or a stalled fan without latching up. The shutdown pin lets the system microcontroller cut supply current to near zero during idle. ## 9-WLCSP — tiny footprint, handle with care It saves board area but demands a clean solder-paste stencil and a reflow profile matched to the 0.4 mm pitch. Store the reels dry — MSL 1 is typical for this package family, but the bag seal date matters. The small footprint also means the PCB layout must keep the output filter and decoupling capacitors close to the bumps; long traces add parasitic inductance that can degrade EMI. ROHS3 compliant, so it clears European and Asian environmental requirements without an exemption.","metaTitle":"SSM2377ACBZ-R7 Class D Audio Amp, 3.17W Mono, 9-WLCSP","metaDescription":"ADI SSM2377ACBZ-R7 Class D mono amplifier delivers 3.17W into 4Ω. 2.5V-5.5V supply, -40°C to 85°C, 9-WLCSP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Class D","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Depop, Differential Inputs, Short-Circuit and Thermal Protection, Shutdown","Output Type":"1-Channel (Mono)","Mounting Type":"Surface Mount","Package / Case":"9-UFBGA, WLCSP","lifecycle_stage":"eol_hot","Voltage - Supply":"2.5V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"9-WLCSP (1.24x1.24)","Max Output Power x Channels @ Load":"3.17W x 1 @ 4Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.74","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.74000","currency":"USD"},{"qty":3000,"price":"$1.20000","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/SSM2377.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output power of SSM2377ACBZ-R7 into 4 ohms?","answer":"The SSM2377ACBZ-R7 delivers 3.17 W into a 4 Ω load from a single channel (mono)."},{"question":"What is the closest functional equivalent for SSM2377ACBZ-R7?","answer":"The SSM2375CBZ-REEL7 is a close functional peer with the same 3.17 W output and similar feature set, but it adds I²C control and a mute pin.
