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 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-Ω speaker .
The gain of the input stage is set by the user-selected input resistor and a 50-kΩ internal feedback resistor
(A
= – 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
V
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
I
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.

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
