description
The TPA0233 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4-
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-
speaker.
The gain of the input stage is set by the user-selected input resistor and a 50-k
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 k
/ RI in SE mode and 125 k/ RI 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.
