The TPA0223 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4-Ω impedance. The amplifier can be reconfigured on the fly to drive two stereo single-ended (SE) signals into head phones. This makes the device ideal for small notebook computers, PDAs, digital personal audio players, anyplace a mono speaker and stereo head.
SE) signals into head phones. This makes the device ideal for small notebook computers, PDAs, digital personal audio players, anyplace a mono speaker and stereo headphones are required. From a 5-V supply, the TPA0223 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-kΩ 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 kΩ/ RI in SE mode and 125 kΩ/ RI in BTL mode. The input ter.
