The TPA0213 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4- speaker.
The gain of the input stage is set by the user-selected input resistor and a 50-k/RI in BTL mode.
The TPA0213 is available in the 10-pin thermally-enhanced MSOP package (DGQ) and operates over an ambient temperature range of ?40°C to 85°C.
