This datasheet describes the TPA0233, 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 headphones. This makes the device ideal for use in small notebook computers, PDAs, digital personal audio players, anywhere a mono speaker and stereo headphones are required. From a 5-V supply, the TPA0233 delivers 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 -3.75 V/V in SE mode or -5 V/V in BTL mode.

the sg3524n/sg3524d/sg3524dr incorporate all the functions required in the construction of a regulating power supply, inverter, or switching regulator on a single chip.
