description
The TPA0233 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4-Ω
impedance. The mono signal is created by summing left and right inputs. 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 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 TPA0233 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
input terminals are high-impedance CMOS inputs, and can be used as summing nodes.
The TPA0233 is available in the 10-pin thermally-enhanced MSOP package (DGQ) and operates over an
ambient temperature range of −40°C to 85°C.
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.
