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