description
The TPA0223 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4- 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 headphones are required. From a 5-V supply, the TPA0223 can deliver 2 W of power into a 4- speaker. The gain of the input stage is set by the user-selected input resistor and a 50-k internal feedback resistor (AV = ญ RF/ RI). The power stage is internally configured with a gain of ญ1.25 V/V in SE mode, and ญ2.5 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, high-impedance CMOS inputs, can be used as summing nodes. The TPA0223 is available in the 10-pin thermally-enhanced MSOP package (DGQ) and operates over an ambient temperature range of ญ40ฐC to 85ฐC.

Terminal Functions
TERMINAL NAME BYPASS GND LIN LO/MOญ MONO-IN RIN RO/MO+ SHUTDOWN ST/MN VDD NO. 4 8 9 10 1 5 6 2 7 3 I O I I O I I I I/O I DESCRIPTION BYPASS is the tap to the voltage divider for internal mid-supply bias. This terminal should be connected to a 0.1-ตF to 1-ตF capacitor. Ground terminal Left-channel input terminal Left-output in SE mode and mono negative output in BTL mode. Mono input terminal Right-channel input terminal Right-output in SE mode and mono positive output in BTL mode SHUTDOWN places the entire device in shutdown mode when held low. TTL compatible input. Selects between stereo and mono mode. When held high, the amplifier is in SE stereo mode, while held low, the amplifier is in BTL mono mode. VDD is the supply voltage terminal.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
