The TPA0213 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4O speaker. The gain of the input stage is set by the user-selected input resistor and a 50-kO/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.
Ideal for Notebook Computers, PDAs, and Other Small Portable Audio Devices
