description

The TPA0211 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4-

Ω

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-

Ω speaker.

The gain of the input stage is set by the user-selected input resistor and a 50-k

Ω internal feedback resistor

BTL mode. Thus, the overall gain of the amplifier is 62.5 k

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.
