Product details

700 mW into 8 Ω — mono speaker or earpiece driver

The TPA701DGNR delivers 700 mW continuous into an 8 Ω load from a single channel, making it a direct fit for portable speaker, headset, or voice-coil applications where a mono Class AB stage is sufficient.

Industrial temperature grade and protection features

On-chip short-circuit and thermal protection prevent latch-up or die damage if the output is accidentally grounded or the load impedance drops below the rated minimum. A dedicated shutdown pin lets the system microcontroller place the amplifier into a low-power idle state when audio is not required.

Package and thermal interface

Housed in an 8-pin HVSSOP with exposed pad (3.00 mm width), the part requires a thermal land on the PCB to conduct heat from the die to the copper plane — without it the output power derates above 70°C ambient.

ROHS3 compliant and free of restricted substances per the current EU directive; no exemption declarations needed for the BOM.
