description
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 small wireless communicators, notebook PCs, PDAs, anyplace a mono
speaker and stereo headphones are required. From a 5-V supply, the TPA0211 can deliver 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
(AV = – RF/RI). 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
Ω/ RI in SE mode and –125 kΩ/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.
