description
The TPA0213 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 use in small notebook computers, PDAs, Digital Personal Audio
players, anyplace a mono speaker and stereo head phones 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-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 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.
