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
headphones. This makes the device ideal for use in small notebook computers, PDAs, personal digital audio
players, anywhere a mono speaker and stereo headphones 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.
AVAILABLE OPTIONS
The DGQ package are available taped and reeled. To order a taped and reeled part, add the
suffix R to the part number (e.g., TPA0213DGQR).
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
