1 / 26 page TPA0211 2-W MONO AUDIO POWER AMPLIFIER SLOS275D – JANUARY 2000 – REVISED NOVEMBER 2002 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Ideal for Wireless Communicators, Notebook PCs, PDAs, and Other Small Portable Audio Devices D 2 W Into 4 Ω From 5-V Supply D 0.6 W Into 4 Ω From 3-V Supply D Wide Power Supply Compatibility 3 V to 5 V D Low Supply Current – 4 mA Typical at 5 V – 4 mA Typical at 3 V D Shutdown Control ... 1 µA Typical D Shutdown Pin Is TTL Compatible D –40°C to 85°C Operating Temperature Range D Space-Saving, Thermally-Enhanced MSOP Packaging 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 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.
