The 700 mW into 8 Ω is the maximum output before clipping; real program material will typically run at lower average power, leaving headroom for peaks. The integrated depop circuitry suppresses turn-on/turn-off clicks, and the short-circuit and thermal protection let the amplifier survive a miswired speaker lead or a stalled airflow condition without failing — useful in a sealed enclosure where you cannot easily replace the part.","metaTitle":"TPA311DR Class AB Mono Amplifier, 700mW into 8Ω, 8-SOIC","metaDescription":"TPA311DR Class AB mono amplifier delivers 700mW into 8Ω. 2.5V-5.5V supply, -40°C to 85°C, depop & protection.
