description

The TPA0253 is a 1-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 8-Ω impedance. The mono signal is created by summing left and right inputs internally. 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 TPA0253 can delivery 1-W of power into a 8-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/ R

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 TPA0253 is available in the 10-pin thermally-enhanced MSOP package (DGQ) and operates over an

ambient temperature range of –40°C to 85°C.
