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
(A_V = − R_F/R_I). 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_I in SE mode and −125 kΩ/R_I 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.
