The amplifier can be reconfigured on the fly to drive two stereo single-ended (SE) signals into headphones. This makes the device ideal for use in small notebook computers, PDAs, personal digital audio players, anywhere a mono speaker and stereo headphones are required. From a 5-V supply, the TPA0213 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 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.
