The TPA0211 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4- impedance. The device is ideal for use in small wireless communicators, notebook PCs, PDAs, anyplace a mono speaker and stereo head phones are required. From a 5-V supply, the TPA0211 can delivery 2-W of power into a 4- speaker.

The gain of the input stage of TPA0211  is set by the user-selected input resistor and a 50-k internal feedback resistor (A_V = R_F/ R_I). The power stage is internally configured with a gain of 1.25 V/V in SE mode, and 2.5 V/V in BTL mode. Thus, the overall gain of the amplifier is 62.5 k/ R_I in SE mode and 125 kW/ RI in BTL mode. The input terminals are high-impedance CMOS inputs, and can be used as summing nodes.

The TPA0211 is available in the 8-pin thermally-enhanced MSOP package (DGN) and operates over an ambient temperature range of 40°C to 85°C.
