Frequently Asked Questions
How much output power does the TPA4861D deliver and at what supply voltage?
The TPA4861D delivers 1W of continuous output power into an 8Ω load when powered from a 5V single supply. Its BTL topology doubles the output swing compared to single-ended designs, so no output coupling capacitor is required, reducing BOM cost.
Can the TPA4861D run from a 3.3V supply?
Yes. The TPA4861D operates across a supply range of 2.5V to 5.5V, making it fully compatible with 3.3V systems. Output power is proportionally lower at 3.3V (approximately 0.35W into 8Ω), which still suits many portable and IoT audio applications.
What applications is the TPA4861D best suited for?
The TPA4861D targets portable and battery-powered audio applications: handheld speakers, multimedia docking stations, intercom modules, and IoT edge nodes. Its 1.3µA shutdown current and single-supply BTL design minimise power consumption when idle, extending battery life.
What are the key differences between TPA4861D and TPA4861DR?
TPA4861D comes in a standard SOIC-8 tube/tray package (50 pcs), while TPA4861DR is the tape-and-reel variant (2500 pcs per reel) for high-volume SMT assembly. Both are electrically identical; the choice depends on production volume and pick-and-place equipment requirements.
Does the TPA4861D include protection features?
Yes. The TPA4861D integrates thermal shutdown protection and output short-circuit protection, safeguarding both the device and connected speakers during fault conditions. These features are especially valuable in consumer products where accidental speaker miswiring can occur.
