| Case | 20-WFQFN Exposed Pad |
At 2.1W per channel into 4Ω, this amplifier is sized for small speakers.
The shutdown pin lets a microcontroller or thermistor cut the output during overtemperature events, and the thermal protection circuit inside the die handles die-level faults before they reach the external shutdown.
