description
The TPA0253 is a 1-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 8-
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 headphones. This makes the device
ideal for use in small notebook computers, PDAs, digital personal audio players, anyplace a mono speaker and
stereo headphones are required. From a 5-V supply, the TPA0253 can deliver 1-W of power into an 8-
speaker.
The gain of the input stage is set by the user-selected input resistor and a 50-k
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
/RI in SE mode and 125 k/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.
